RCX7050P ------- smd selectable frequency crystal oscillator ------- ------- high performance xo in a 7 x 5 mm surface mount package with selectable output frequency ------- product description ------- the RCX7050P selectable xo combines low rms phase jitter and tight stability with the ability to select the output frequency from up to four factory-configured frequencies by controlling two frequency select (fs) pins (e.g. 125 or 156.25 mhz). this enables reductions in part count and built-in upgrade paths to increase design flexibility and reduce costs. ------- applications consumer communications base stations dsl/adsl ethernet wi-fi wimax/w-lan ------- features selectable output frequencies (up to 4) low power differential outputs <1ps integrated rms phase jitter (12 khz to 20 mhz) wide frequency range cmos, lvpecl, lvds, or hcsl output options fast sample turnaround ------- specifications ----- 1.0 specification references line parameter description 1.1 model description RCX7050P xo 1.2 reference number 1.3 rakon part number ----- 2.0 frequency characteristics line parameter test condition value unit 2.1 frequency 1 fs1 = 0, fs2 = 0. see pin connections for details 8 to 1500 mhz 2.2 frequency 2 fs1 = 1, fs2 = 0. see pin connections for details 8 to 1500 mhz 2.3 frequency 3 fs1 = 0, fs2 = 1. see pin connections for details 8 to 1500 mhz 2.4 frequency 4 fs1 = 1, fs2 = 1. see pin connections for details 8 to 1500 mhz 2.5 output switching time 0.1 max ms 2.6 operating temperature range -40 to 85 c 2.7 frequency stability including temperature range, supply variation, load variation and 10 years aging at 25c 20 to 50 ppm 2.8 temperature stability temperature range only 10 to 20 ppm ----- page 1
