the horizontal frequency (f h ) = 15.625 khz for 625 line systems and 15.734264 khz for 525 line systems. these relationships are obtained by the use of a phase locked loop and the internal programmed divider chain, see fig.3(a). lock to an external signal source the following methods can be used to lock to an external signal source: 1. sync. lock slow; the line frequency is locked to an external signal. the line and frame information are extracted from the external sync. signal and used separately in the lock system. the line information is used in a phase-locked loop where external and internal line frequencies are compared by the same phase detector as is used for the subcarrier lock. the external frame information is compared with the internal frame in a slow lock system; mismatch of internal and external frames will result in the addition or suppression of one line depending on the direction of the fault. the maximum lock time for frame lock is 6.25 s, see fig.3(b). 2. sync. lock fast. a fast lock of frames is possible with a frame reset which is extracted out of the incoming external sync. signal, see fig.3(c). 3. sync. lock with external reference. lock of an external sync. signal to the line frequency with an external line reference to make possible a shifted lock. the secam (1 and 2) 282f h paln 229.2516f h ntsc (1 and 2) 227.5f h palm 227.25f h pal b/g 283.7516f h subcarrier input is, in this case, used as an external input for the horizontal reference, see fig.3(d). selection of lock mode lock mode is selected using the inputs lm0 and lm1 as illustrated in the table below. lm0 lm1 selection 0 0 lock to subcarrier 0 1 slow sync. lock external h ref 1 0 slow sync. lock internal h ref 1 1 fast sync. lock internal h ref january 1990 6 philips semiconductors product speci?cation universal sync generator (usg) SAA1101 the different lock modes are illustrated by the following figures: fig.3 (a) lock to subcarrier. fig.3 (b) slow sync lock, internal h ref fig.3 (c) fast sync lock, internal h ref fig.3 (d) slow sync lock, external h ref handbook, halfpage mgh193 n f h line oscillator fso fsi osco osci SAA1101 sub- carrier oscillator ph lm1 lm0 logic 0 logic 1 10 65 8 2 1 9 handbook, halfpage mgh194 n f h line oscillator ecs osco osci SAA1101 ph lm1 lm0 logic 0 logic 1 10 65 8 11 9 handbook, halfpage mgh195 n f h line oscillator ecs osco osci SAA1101 ph lm1 lm0 logic 1 logic 1 10 65 8 11 9 handbook, halfpage mgh192 n f h line oscillator t h ref ecs fsi h d osco osci SAA1101 ph lm1 lm0 logic 0 logic 1 10 65 8 22 11 1 9 january 1990 7 philips semiconductors product speci?cation universal sync generator (usg) SAA1101 lock with horizontal and vertical signals (slow lock modes only) it is possible to use horizontal and vertical signals instead of composite sync signals. the connections in this situation are: the external horizontal signal is connected to the ecs input (pin 11) and the vertical signal to the rr input (pin 12). the high time of the horizontal pulse must be less than 14.4 m s, otherwise it will be detected as being a vertical pulse and will corrupt the vertical slow lock system. selection of clock frequency the clock frequency is selected using the cs0 and cs1 inputs as illustrated below. where the horizontal frequency, f h = 15.625 khz for 625 lines and 15.734264 khz for 525 lines. oscillators the subcarrier oscillator has fsi as its input and fso as its output. it is always used as a crystal oscillator with a series resonance crystal with parallel load capacitor. the maximum frequency, f max = 5 mhz and the load capacitor, c l =10 < c l < 35 pf. the clock oscillator has osci as its input and osco as its output. it can be used with an lc oscillator or a series resonance crystal with parallel load capacitor (fig.4). the maximum frequency, f max = 24 mhz and the load capacitor, c l = 10 < c l < 35 pf. selection of 625/525 (standard; interlaced mode) or 624/524 lines (non-interlaced mode) selection is achieved using the norm input. when norm = 0, 625/525 (standard) lines are selected; when norm = 1, 624/524 line are selected. output dimensions all push-pull outputs: standard output 2 ma. white measurement pulse, wmp: 3-state output 2 ma. phase detector, ph: 3-state output 2 ma. cs0 cs1 frequency 625 lines 525 lines units 0 0 160f h 2.5 2.517482 mhz 0 1 160f h 5 5.034964 mhz 1 0 960f h 15 15.104893 mhz 1 1 1440f h 22.5 22.657340 mhz january 1990 8 philips semiconductors product speci?cation universal sync generator (usg) SAA1101 selection of tv system selection of the required tv system is achieved by the x, y and z inputs as illustrated by the following table. limiting values limiting values in accordance with the absolute maximum system (iec 134) note 1. input voltage should not exceed 7 v. system xy z secam1 0 0 0 paln 0 0 1 ntsc1 0 1 0 palm 0 1 1 secam2 1 0 0 (with identi?er) pal b/g 1 0 1 ntsc2 1 1 0 (short blanking) symbol parameter min. max. unit v dd supply voltage - 0.5 + 7v v i input voltage - 0.5 v dd + 0.5 (1) v i i maximum input current - 10 ma i o maximum output current - 10 ma i dd maximum supply current in v dd - 25 ma p tot maximum power dissipation - 400 mw t stg storage temperature range - 55 + 150 c fig.4 crystal oscillator circuit. handbook, halfpage mgh196 SAA1101 6 5 500 k w 1 k w 39 pf 39 pf 15 mhz osci osco january 1990 9 philips semiconductors product speci?cation universal sync generator (usg) SAA1101 characteristics v dd = 4.5 to 5.5 v;

solder at this temperature must not be in contact with the joint for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg max ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. r epairing soldered joints apply a low voltage soldering iron (less than 24 v) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be up to 5 seconds. so r eflow soldering reflow soldering techniques are suitable for all so packages. reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several techniques exist for reflowing; for example, thermal conduction by heated belt. dwell times vary between 50 and 300 seconds depending on heating method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 minutes at 45 c. w ave soldering wave soldering techniques can be used for all so packages if the following conditions are observed: a double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. the longitudinal axis of the package footprint must be parallel to the solder flow. the package footprint must incorporate solder thieves at the downstream end. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 c within 6 seconds. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. r epairing soldered joints fix the component by first soldering two diagonally- opposite end leads. use only a low voltage soldering iron (less than 24 v) applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c. january 1990 18 philips semiconductors product speci?cation universal sync generator (usg) SAA1101 definitions life support applications these products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify philips for any damages resulting from such improper use or sale. data sheet status objective speci?cation this data sheet contains target or goal speci?cations for product development. preliminary speci?cation this data sheet contains preliminary data;
