23.2. Genlock Controller IP Parameters

The IP offers compile- and run-time parameters
Table 383.   Genlock Controller IP Parameters
Parameter Values Description
Configuration
Number of reference clock 1 to 4 The number of reference clocks as source for VCXO tracking.
PFD Parameters
Differential value size 12 to 27 The size of the PFD clock counters and output difference value.
Differential value size 8 to 24 The number of bits for the error counter to calculate the difference between two samples of output difference values.
Sample period counter size 4 to 32 Select how many least significant bits (LSB) the IP uses for the sample period counter.
LPF Parameters

Negative Only

CPU selectable

Select the derivative gain modes.

LPF to DAC LSB Position 0 to 3 Select the LPF output to DAC least significant bit position. Allows the IP to ignore error wobble by moving the LSB.
VCXO Lock Confidence Counter Size 6 to 32 The lock confidence count size in bits. The number of successive samples with no error before the IP indicates lock.
DAC Parameters
Resolution 8 to 24 PWM DAC value output size. Defines the precision of the value to drive the DAC. Higher number of bits indicates more resolution, and longer time to lock. Fewer bits could decrease the locking time but increase the VCXO jitter.
PMW Output Clock Divider 3 to 4096

The IP divides the VCXO clock by this value (and then by an additional 2). The IP uses the value to drive the DAC output pin.

The value should be low enough to provide a fast response, but not too low to increase VCXO jitter.

Debug
Enable Debug 0 to 2

Extra CPU debugging registers:

  • 0 = Debug off
  • 1 = VCXO and reference clock measurement
  • 2 = PFD status value
Enable Genlock Profiler

Profiler enabled

Profiler disabled

The profiler allows you to measure the difference between receive and transmit video pixel clocks.

The profiler also measures the latency between receive and transmit start-of-frame (SOF) toggle signals.

CPU Clock Frequency 1 MHz to 1 GHz CPU clock frequency for measuring VCXO and reference clock frequencies for debugging,
