receive volume control
The receive volume control block acts as an attenuator with a range of –18 dB to 0 dB in two dB steps for control
of the receive channel volume. The receive volume control gain defaults to 0 dB.
receive filter and PGA
The receive filter is a digital filter that meets CCITT G.714 requirements with a high-pass filter that is selectable
through the I2C interface. The device operates in either the 13-bit linear or 8-bit
-law companded mode, which
is selectable through the I2C interface. The gain defaults to –6 dB.
digital modulator and filter
The second-order digital modulator and filter convert the received digital PCM data to the analog output required
by the earphone interface.
earphone amplifiers
The analog signal can be routed to either one of two earphone amplifiers, one with differential output (EAR1ON
and EAR1OP) and one with single-ended output (EAR2O). Clicks and pops are suppressed for EAR1
differential output only.
