General Description
AS3502 is a high performance 13-bit linear feature
Codec/Filter with 8 kHz sampling rate specifically
tailored to implement all analogue frontend functions
of battery powered digital terminals. It includes a
programmable analogue interfaces for handset and
handsfree operation with a minimum amount of
external components.
The Codec function of AS3502 uses Sigma-Delta (
Σ
)
modulation conversion techniques with 2nd order
modulators and an over sampling rate of 128 for
excellent signal to noise performance. The AS3502
exceeds all CCITT G712 recommendations and the
European ETSI prETS 300085 recommendations.
Digital gain setting stages for transmit and receive
allow to compensate for transducer tolerances and to
set up a handsfree function under software control. A
programmable tone generator allows to generate
DTMF/Call-Progress Tones and alert sounds required
in digital terminals. All programmable functions of
AS3502 are controlled by a 4-wire serial control port
that easily interfaces to any popular micro controller.
The interface to the digital world is accomplished by a
serial PCM interface that supports 16-bit linear format
or 8-bit A-Law format for both non-delayed and
delayed frame synchronzation modes.
