Pin Description
Clock output from VCO. Output frequency equals the input frequency times multiplier.
Supply pin for CLK output buffer. Sets output clock amplitude. Connect to 2.5V or 3.3V.
Connect to +3.3V or +5V. Must match other VDDs.
Connect to +3.3V or +5V. Must match other VDDs.
Connect to +3.3V or +5V. Must match other VDDs.
Crystal connection. Connect to a 10 - 27 MHz fundamental parallel mode crystal.
Multiplier select pin 1. Determines CLK output per table above. Internal pull-up.
