Does AD8196 and AD8197 has retimer function

Hi,

  AD8196/AD8197 does not support any retimer functionality and also we don't find any part which can support HDMI Switch(4:1/2:1) along with retimer function.

  But you can interface "AD8196/AD8197" part with any retimer chip (PS8419/TMDS181 ). .

  Please refer this thread https://ez.analog.com/video/f/q-a/103410/adv7511-output-issue here one of the customer have been using "TMDS181" retimer.

  Reference: https://www.ti.com/lit/ds/symlink/tmds181.pdf?ts=1666855659900

 Note: AD8197 switching logic has three modes: Quad mode (a quad 4:1 switch) / Dual mode (a dual 8:1 switch), and Single mode (one 16:1 switch).
The primary function of the AD8197 is to switch one of four (HDMI or DVI) single-link sources to one output.Each HDMI/DVI link consists of four differential, high speed channels and four auxiliary single-ended, low speed control signals.
  Data Rate: Supports 250 Mbps to 2.25 Gbps data rates
  Supports 25 MHz to 225 MHz pixel clocks
  Equalized inputs for operation with long HDMI cables (20 meters at 2.25 Gbps)

Thanks,

Hello,

The AD819x device family do not have retimer circuits. You may browse clock/data recovery or retimer ICs in this link: analog.com/en/parametricsearch/10771#/

May we know why you need retiming? AD8196 and AD8197 are capable of equalization to compensate for operation with long cables (20 meters at 2.25 Gbps).
