PECL/LVPECL HF XO
AB-X29SXXX-X Series
Description
The
AB-X29SXXX Series
of crystal oscillators (XO) provides high frequency with PECL/LVPECL
complementary outputs. The outputs can be disabled for test automation or combining multiple clocks. The
device does not use any frequency multiplication, providing exceptionally low Phase Noise and Jitter. It is
packaged in a miniature, FR-4 based 9x14 mm SMD package.
Applications and Features
• Wide frequency range – 12.0MHz to 280.000MHz
• 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, Low Jitter
• No Multiplication
• SONET ±20ppm overall free-run stability available
• High shock resistance, to 1000g
• COTS/Dual use
