DS125DF410: How to set CTLE to maximum Gain

Other Parts Discussed in Thread: DS125DF111,

Hi Team,

Please allow me to ask you how to set the CTLE gain to maximum.

Our customer needs higher gain setting for signal conditioning.

I believe adaptive CTLE gain table doesn't have the maximum gain setting of +34dB boost at 6.25GHz.

If this is true, which value would be the maximum boost setting in REG 0x03 ?

Would it be REG 0x03 = 0xFF when used in fixed CTLE mode ?

DS125DF111 datasheet shows register setting of "0xF9" is +33dB@6.25GHz in the adaptive gain table.

However, DS125DF410 datasheet shows "0xA5" as maximum gain in tthe adaptive gain table.

Best Regards,

Kawai
