PLL lock time constant capacitor connection.
Power supply connection for the charge pump. Connect to +3.3V DC
analog.
Ground connection for the charge pump. Connect to analog GND.
Control voltage to set the loop bandwidth of the integrated reclocker.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select the timing mode of the device.
When set HIGH, the device will lock the internal flywheel to the embedded
TRS timing signals in the parallel input data.
When set LOW, the device will lock the internal flywheel to the externally
supplied H, V, and F input signals.
