DS90UB929-Q1: DS90UB929+DS90UB926

Part Number: DS90UB929-Q1

Dears,

Our customer use DS90UB929-Q1+ DS90UB926 -Q1. The related configuration is as following:

DS90UB929-Q1: MODE_SEL[0] = 000 ,MODE_SEL[1] = 000,PDB= high, INTB=high, REM_INTB=low, The input is 720P(1280*720/60HZ). Default register configuration.

DS90UB926-Q1:MODE_SEL = 0000,PBD,OEN,OSS_SEL are all high, lock is high, pass is low.   Default register configuration.

When power up, all voltage is no problem, but there is no output of DS90UB926, the output data and the clock are all low. 

So do they work normally if 929 and 926 are with default register configuration ? Could you give me some advice?

Thank you very much.

 Best regards

Kailyn
