8.2.1.65. RX_CLK_LOSS_DETECT

Offset: 0x50
Default: IP Param
Description: RX PCS Clock Loss Detect
Bit Name Access Description
7:0 RX_CLK_LOSS_DETECT Read Write *

RX PCS Clock Loss Detect.

Timeout for D-PHY PCS to detect absence of Clock transitions and deassert RxClkActiveHS on the PPI bus. This is different from the D-PHY specification TCLK-MISS. Min value should be equal to 3 x RX_CLK-period (in ns).

Delay computations (approx):

- TRX_CLK_LOSS_DETECT = (RX_CLK_LOSS_DETECT + 6) * Core_CLK_period.
Note: * Can be configured as Read Only during IP generation to save resources.
