6.2. Transmitter Protocol Signals

Table 18.  Transmitter Protocol Signals—Synchronous to tx_pclk
Note: S = Indicates the number of 20-bit interfaces; 4 for multi-rate (up to 12G) mode and 1 for other modes.
Signal Width Direction Description

Enables CRC insertion for all modes except SD-SDI.

Note: Not applicable for transceiver only configurations.
tx_enable_ln

1

Input

Enables LN insertion for all modes except SD-SDI.

Note: Not applicable for transceiver only configurations.
tx_std

3

Input

Transmitter video standard with multiplexed 10-bit parallel interface:

  • SD-SDI = 000
  • HD-SDI = 001
  • 3G-SDI Level A 10-bit Multiplex= 011
  • 3G-SDI Level B 10-bit Multiplex= 010
  • 6G-SDI 10-bit Multiplex Type 1 = 101
  • 6G-SDI 10-bit Multiplex Type 2 = 100
  • 12G-SDI 10-bit Multiplex Type 1 = 111
  • 12G-SDI 10-bit Multiplex Type 2= 110
Note: Applicable for 3G-SDI, and dual-rate, triple-rate, and multi-rate modes.

For 6G and 12G-SDI, there are a few modes of data mapping for different image formats, and each of these modes requires a different type of 10-bit Multiplex interface. It is important to find out which mode you are transmitting and assign the proper value of the 10-bit Multiplex interface of that mode.

For instance, Single link 6G-SDI has three modes of Data Mapping (Mode 1 – Mode 3). Mode 2 and Mode 3 are assigned to 10-bit Multiplex Type 1 according to SMPTE ST2081-10.

As for Single Link 6G-SDI Mode 1, it is assigned to 10-bit Multiplex Type 2.

This signal is only applicable for 3G, dual rate, triple rate and multi rate.
