OP4005B1-041003 ? ? quartz saw stabilized differential output technology ? very low jitter fundamental-mode operation at 622.08 mhz ? voltage tunable for phase locked loop applications ? timing reference for optical data communications systems the OP4005B1 is a voltage-controlled saw clock (vcsc) designed for phase-locked loop (pll) applications in optical data communications systems. the differential outputs of the OP4005B1 are generated by high-q, fundamental mode quartz surface acoustic wave (saw) technology. this technique provides very low output jitter and phase noise, plus excellent immunity to power supply noise. the OP4005B1 differential outputs fea- ture 1% symmetry, and can be dc-configured to drive a wide range of high-speed logic families. the OP4005B1 is packaged in a hermetic metal-ceramic lcc. absolute maximum ratings rating value units dc suppy voltage 0 to 5.5 vdc tune voltage 0 to 5.5 vdc case temperature -55 to 100 c 622.08 mhz optical timing clock OP4005B1 caution: electrostatic sensitive device. observe precautions for handling. cocom caution: approval by the u.s. department of com merce is required prior to export of this device. notes: 1. unless otherwise noted, all specifications include the combined effects of load vswr, v cc and t c . 2. net tuning range after tuning out the effects of initial manufacturing tolerances, vswr pushing/pulling, v cc , t c and aging. 3. the internal design, manufacturing processes, and specifications of this device are subject to change without notice. 4. specified only for a balanced load with a vswr < 1.2 ( 50 ohms each side), and a v cc = 3.0 vdc. 5. symmetry is defined as the width in (% of total period) measure at 50% of the peak-to-peak voltage of either output. 6. jitter and other noise outputs due to power supply noise or mechanical vibration are not included in this specification excep t where noted. 7. applies to period jitter of either differential output. measured with a tektronix csa803 signal analyzer with at least 1000 s amples. 8. one or more of the following united states patents apply: 4, 616,197; 4,670,681; 4,760,352. characteristic sym notes minimum typical maximum units operating frequency absolute frequency f o 1 622.08 mhz tuning range 2 100 ppm tuning voltage 1 0 3.3 vdc tuning linearity 1 5 % modulation bandwidth 200 khz q and q output voltage into 50 w (vswr 1.2) v o 1,3 0.60 1.1 v p-p operating load vswr 1,3 2:1 symmetry 3, 4, 5 45 55 % harmonic spurious 3, 4, 6 -15 dbc nonharmonic spurious 3, 4, 6, 7 -60 dbc phase noise @ 100 hz offset 3, 6 -70 dbc/hz @ 1 khz offset 3, 6 -100 dbc/hz @ 10 khz offset 3, 6 -125 dbc/hz noise floor 3, 6 -150 dbc/hz q and q jitter rms jitter (10khz to 80mhz) 3, 4, 6, 7 0.1 ps no noise on v cc 3, 4, 6, 7 12 ps p-p 200 mv p-p noise, from 1 mhz to ? f o on v cc 3 12 ps p-p input impedence (tuning port) 8 10 k w output dc resistance (between q & q ) 1, 3 50 k w dc power supply operating voltage v cc 1, 3 3.13 3.3 or 5.0 5.25 vdc operating current i cc 1, 3 70 ma operating case temperature t c 1, 3 -40c +85c c lid symbolization (yy=year, ww=week) rfm OP4005B1 yyww smc-08a electrical characteristics
