Notes:
1. Differential Modes: LVPECL/LVDS/CML. Refer to AN255, AN256, and AN266 for further information.
2. For best jitter and phase noise performance, always choose the smallest KV that meets the application’s minimum APR
requirements. See “AN266: VCXO Tuning Slope (KV), Stability, and Absolute Pull Range (APR)” for more information.
3. See “AN255: Replacing 622 MHz VCSO devices with the Si550 VCXO” for comparison highlighting power supply
rejection (PSR) advantage of Si55x versus SAW-based solutions.
