Description
Read/write bit for changing digital state of Tx Rate_Select RS(1) function
Always set to zero. Value of zero indicates Power Level 1 operation (1 Watt
max)
Unused. This device supports power level zero (1 Watt max) only.
Description
Defi nes SFP incoming electrical Tx equalization setting for Tx_Rate = High [ie. RS(1)=High]
The SFP transceiver will support two EQ settings based on LSB. With LSB = 0, the Tx input
EQ is set to 0dB (no EQ). With LSB = 1, the Tx input EQ is set to 6dB gain at 7 GHz.
Writing FFh to this byte resets to factory settings, EQ = 0dB.
Defi nes SFP incoming electrical Tx equalization setting for Tx_Rate = Low [ie. RS(1)=Low]
The SFP transceiver will support two EQ settings based on LSB. With LSB = 0, the Tx input
EQ is set to 0dB (no EQ). With LSB = 1, the Tx input EQ is set to 6dB gain at 7 GHz.
Writing FFh to this byte resets to factory settings, EQ = 0dB.
Defi nes SFP output electrical Rx pre-emphasis setting for Rx_Rate = High [ie. RS(0)=High]
The SFP transceiver will support 8 Pre Emphasis amplitude settings in the lower 3 bits of
this byte. Emphasis can be varied from 0dB to 6dB in eight non-linear steps. A value of 0
results in 0dB emphasis.
Writing FFh to this byte resets to factory settings, EMPH = 0dB.
Defi nes SFP output electrical Rx pre-emphasis setting for Rx_Rate = Low [ie. RS(0)=Low]
The SFP transceiver will support 8 Pre Emphasis amplitude settings in the lower 3 bits of
this byte. Emphasis can be varied from 0dB to 6dB in eight non-linear steps. A value of 0
results in 0dB emphasis.
Writing FFh to this byte resets to factory settings, EMPH = 0dB.
