Hi Team,

Please allow me to ask you about DS64BR401 EQ DEM gain setting.

By default, DEM register is set as 0x03, however, DEM gain is not listed in the description column. What would be the DEM gain for the default register value ?

Best Regards,

Hi Kawai-san,

This device is a legacy repeater, so it will take us some time to reference our design documents. We will respond to you by 11/27 after we return from the US Thanksgiving Holidays.

Hi Kawai-san,

When using the SMBus programming configuration the default setting of 0x03 should provide ~ -3.5dB of de-emphasis.

The values highlighted in the table tend to give the best results.

Regards,

Lee
