CRYSTAL OSCILLATORS Data Sheet 0645A AB-X29NXXX Series PECL/LVPECL UHF XO Description The AB-X29NXXX Series of crystal oscillators (XO) provides ultra high frequency with PECL/LVPECL complementary outputs. The outputs can be disabled for test automation or combining multiple clocks. The device is based on low noise analog harmonic frequency multiplication, providing exceptionally low Phase Noise and Jitter. It’s packaged in a miniature, FR-4 based 9x14 mm SMD package Applications and Features • • • • • • • Fiber Channel; 10 GbE; Infiniband; Network Processors; SONET/SDH High Reliability – NEL HALT/HASS qualified for crystal oscillator start-up conditions Extremely Low Phase Noise and Jitter Frequency Range to 1,000 MHz RoHS compliant, Lead Free Construction SONET ± 20 ppm overall stability available High Shock Resistance, to 1.000 G Creating a Part Number AB - X 29N X X X Package code AB 6 pad 9x14 mm SMD Operating Voltage 0 5.0 V ± 5% A 3.3 V ± 5% Enable Option L Enable Low N N/C Frequency Stability, ppm E ±20 F ±25 G ±32 H ±50 J ±100 K Customer specific Temperature Range, ºC A 0 to 50 B 0 to 70 C -20 to 70 D -40 to 85 9 Customer Specific 357 Beloit Street, P.O.
