The read pointer increments at the DAC_DCLKIN rate whereas the write pointer increments at the divided DAC_CLK rate. While the frequencies of these 2 clocks are expected to be the same, relative phase drifts can cause this relative difference of 4 positions to drift. When the EN_FIFO_COLLISION_DET bit is set, a collision condition is detected when the relative difference 32 REGISTER DESCRIPTIONS Copyright © 2011–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AFE7222 AFE7225 |
