Notes:
Offset adjustment for each channel is available by loading a 16-bit word into the receive offset register via the
serial interface.
Optimally, anti-alias filtering should be carried out as much as possible prior to any AGC function before the
receive inputs. This allows the AGC to act on a reduced bandwidth signal and thereby improve the relative
magnitude of the wanted part. The device has been designed to reduce the complexity of any external anti-
alias filter as much as possible and a 4-pole Butterworth with a -3dB point at about 60kHz should be adequate.
The internal anti-alias filter, if used, cannot provide the required 110dB attenuation at 2.3MHz and must be
supplemented by external filtering. The most simple supplementary system may be a one- or two-pole filter
before the AGC and an RC network after the AGC with a -3dB point on each filter of about 200kHz.
