Am79C30A/32A
Digital Subscriber Controller (DSC) Circuit
Table 23: Amplitude Gain Coefficients on page 27 of
the Am79C30A/32A final data sheet has the following
changes:
The tone gain block was intended to provide amplitude
steps of 2 dB with a tolerance of approximately 0.5 dB.
The following additional codes can also be used:
–17 dB = Hex 33
–11 dB = Hex 23
–5 dB = Hex 13
The updated Table 23 reads as follows:
