Bitslip logic
WebWhen this signal is logic high, the internal logic skips PMA and performs a parallel loopback after RS-FEC. lat_bitslip [21:0] Output: Indicates latency introduced by RX bitslip logic in soft PCS. WebUsing BITSLIP allows for word framing by providing a control signal generated in the FPGA fabric and by parallel word logic running at parallel word clock rates. The Lx_BIT_SLIP …

WebThe rx_bitslip_ctrl signal has the following requirements: The minimum pulse width is one period of the parallel clock in the logic array. The minimum low time between pulses is one period of the parallel clock. The signal is an edge-triggered signal. The valid data is available four parallel clock cycles after the rising edge of rx_bitslip_ctrl. Web// Documentation Portal .

WebMar 28, 2014 · Here is a screenshot showing the signals on some of the ports of a cascaded (width expansion) ISERDES-pair: This example is actually from a simulation of the example design that is generated by Coregen (SelectIO Interface Wizard). Width is 14 bits, DDR mode. The VHDL code is inserted below this message. The signal iserdes_q_vec is a … 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.
