DP83TC811R-Q1: SNR different statemtents in datasheet

Expert 6710 points
Part Number: DP83TC811R-Q1

Datasheet on page 25 says: 

Signal-to-noise ratio is accessible through the SNR Register 0x0197 – Signal-to-Noise Ratio Result Register. To

convert this binary register field to dB, follow these steps:

1. Convert bits[7:0] in register 0x197 to decimal form

2. Divide decimal value by 10

3. Result is SNR (dB) reading

 

Datasheet on page 65 in table 51 says:

 BIT 8:0 Signal to Nois Ration (10*SNR)…

 

Which statement is correct or why are the statements different?

 

Thank you,

Andreas
