FULL SIZE D.I.L. M package CRYSTAL OSCILLATORS ECLPS LVPECL 3.3V M2980, M2984, M2985, M2988 Thru-Hole / Gull Wing Description Commercial: 0º to 70ºC 10 MHz to 410 MHz Generates complementary 3.3V LVPECL output waveform which is optimized for low jitter for telecom applications GUARANTEED SUPER-LOW JITTER These oscillators use fundamental or overtone crystals to achieve jitter of less than 10 ps RMS, and 35 ps pk-pk, from positive edge to positive edge. Multiplying techniques are not used. FEATURES • Frequency range is 10-410 MHz • Stability options from ±100 ppm to ±20 ppm • Start up time less than 5 ms • Guaranteed start-up with ramping DC Supply • Internal bypass capacitor delivers superior waveform characteristics • Complementary LVPECL outputs • 5x7mm SMD version of this product is available in our R2980 models These 3.3 volt thru hole LVPECL models feature jitter of 35 ps, peak-to-peak from positive edge to positive edge. This is accomplished by using AT-cut crystals operating in their fundamental or overtone modes. No frequency doubling, tripling or phase-lock-loop multipliers are used, ensuring the very lowest jitter limited only by the LVPECL logic.Two outputs support differential drive at 50 ohms, assuring signal integrity even when transmitted over long paths. TYPICAL APPLICATIONS • Super-low jitter minimizes data loss and dropped packets in telecom and data networking applications LVPECL 3.3 V DOT DENOTES PIN 1 DOT DENOTES PIN 1 .800 – .005 .800 – .005 .200 MAX .215 MAX .018 – .001 .060 TYP .300 – .005 .008/025 .15 MIN Model Frequency Stability M2980 ±100 ppm M2984 ±25 ppm M2985 ±50 ppm M2988 ±20 ppm .200 MAX .270 MAX .018 – .001 .400 .600 – .005 Pin 1 .600 – .005 .100 – .005 Pin 7 Pin 1 Pin 7 .520 – .005 .300 –. 005 .500 – .005 .300 –. 005 .150 Pin 14 Pin 8 .250 MAX GLASS INSULATORS (4) Fig. 1 “M-1” Package Pin 14 Pin 8 GLASS INSULATORS (4) on .48 x .18 ctrs.
