5.1.4.1. Setting the Transmitter Output Clock Parameters
You can specify the relationship of tx_outclock to the tx_out data using these parameters:
- Desired tx_outclock phase shift (degrees)
- Tx_outclock division factor
The parameters set the phase and frequency of the tx_outclock based on the fast_clock, which operates at the serial data rate. You can specify the desired tx_outclock phase shift relative to the tx_out data at 45° increments of the fast_clock. You can set the tx_outclock frequency using the available division factors from the drop-down list.
Edge-Aligned tx_outclock to tx_out
For rising tx_outclock edge-aligned to the MSB of the serial data on tx_out, specify 0° phase shift.
Center-Aligned tx_outclock to tx_out
To specify center-aligned relationship between tx_outclock and the MSB of the serial data on tx_out, specify 180° phase shift.
- Phase shift values from 0° to 315° position the rising edge of tx_outclock within the MSB of the tx_out data.
- Phase shift values starting from 360° position the rising edge of tx_outclock in serial bits after the MSB. For example, a phase shift of 540° positions the rising edge in the center of the bit after the MSB.
Use the Tx_outclock division factor drop-down list to set the tx_outclock frequency.
