6.3.3 Data Transmission Latency

The data transmission latency of the TLK2711-SP is defined as the delay from the initial 16-bit word load to the serial transmission of bit 0. The transmit latency is fixed after the link is established. However, due to silicon process variations and implementation variables such as supply voltage and temperature, the exact delay varies slightly. The minimum transmit latency td(Tx latency) is 34 bit times; the maximum is 38 bit times. Figure 6-2 shows the timing relationship between the transmit data bus, TXCLK, and serial transmit pins.
