DS125BR111: DS125BR111 datasheet question

Part Number: DS125BR111

Hi Sir,

Q1. DS125BR111 can support SATA3 which is 3GHz, but I don't see the equalizer compensate table to mention about the EQ value on 3GHz,

       Can you please help to clarify the exactly value of equalizer in 3GHz?

Q2. What is the entire channel means in below picture? is it from HOST to end device? or only HOST to DS125BR111?

       could you please help to clarify it?

Thank you

  • Hi Anne,

    1). Please note table 4 of the DS125BR111 data sheet. At 3GHz EQ gain would be between gains at 2.5GHz and 4GHz. For example with EQ settings of 0x00 3GHz gain would be at 2.6dB.

    2). By entire channel we mean from host to end device since DS125BR111 CTLE receiver can compensate for 10dB loss at 6GHz.
