ADN4624 HDMI reference design

Question

Hi ADI team 
 In ADN4624 datasheet Page 19,show the HDMI example diagram 
 I'd like to know the capacitor and resistor value,is the detail schematic document? 
 Thanks

Hi Larson, 
 We have not yet published a complete tested solution using ADN4624 to isolate HDMI, but I can refer you to our circuit note using ADN4654: 
 CN0422 Circuit Note | Analog Devices 
 Using ADN4624 will be similar but allowing higher bandwidth so that 1080p resolution is practical (or maybe half-frame rate 4K). 
 Some suggested optimizations of that circuit would be to only use the AC coupling capacitors on the outputs (don't place the 10k pull-up/pull-down resistors), and on the inputs, the pull-ups can be to the 1.8V VDD1 supply. The LVDS common mode biasing can be simplified, by omitting the 10k pull-up/pull-downs and instead splitting the termination resistor (connecting between two resistors to 1.8V). With this arrangement, it should be sufficient to terminate simply with 50 Ohm to 1.8V on Din+ and on Din-, after the AC coupling cap (with no pull-up before it). 
 Best regards, 
 Conal
