OUT
LVCMOS/LVTTL Control Channel UART Input. TX is internally pulled up to V
Open-Drain Lock Output. LOCK asserts high to indicate PLLs are locked with correct serial-word
boundary alignment. LOCK asserts low to indicate PLLs are not locked or incorrect serial-word
boundary alignment was detected. Pull up to V

LVCMOS/LVTTL Data Outputs
Output Supply Voltage. V
0.1µF and 0.001µF capacitors in parallel as close as possible to the device with the smallest value
capacitor closest to V
Output Supply Ground
Spread-Spectrum PLL Supply Voltage. Bypass V
capacitors in parallel as close as possible to the device with the smallest value capacitor closest to
