Receiver Output Amplitude Control Code Description

Control registers 228 through 233 permit output signal amplitude selection. Four bit code blocks (either bits 7 through

4 or 3 through 0 where bit 7 or 3 is the msb) are assigned to each channel. Codes 1xxx are reserved. Code 0111 calls for

full scale signal amplitude and code 0000 calls for minimum signal amplitude. See table below.

Receiver Output De-emphasis Control Code Description

Control registers 234 through 239 permit output de-emphasis selection. Four bit code blocks (either bits 7 through 4 or

3 through 0 where bit 7 or 3 is the msb) are assigned to each channel.

Codes 1xxx are reserved.

Code 0111 calls for full scale, 6 dB, de-emphasis and code 0000 calls for no de-emphasis.

Intermediate code values yield intermediate de-emphasis levels
