In digital transmission, bit slip is the loss or gain of a bit or bits, caused by clock drift – variations in the respective clock rates of the transmitting and receiving devices. One cause of bit slippage is overflow of a receive buffer that occurs when the transmitter's clock rate exceeds that of the receiver. This causes one or more bits to be dropped for lack of storage capacity. WebEach I/O logic tile in the 7 series FPGAs contains an 8-bit ISERDES and an 8-bit OSERDES. The ISERDES and OSERDES from two adjacent blocks (master and slave) can be cascaded to give a ... obtained from the incoming pixel clock is also used together with the Bitslip feature of the ISERDES to generate parallel data that is in the correct word ...
