GENERAL DESCRIPTION
This
IP
Core
has
been
developing
for
AFE(Analog-front-end)
Function
of
Voice
Signal
Processing with 14bit 8KHz Voice Codec. The Core
consists
of
14bit
linear
monolithic
PCM
CODEC/transmit and receive band-pass filters utilizing
the Sigma-Delta A/D and D/A conversion Architecture.
It offers a number of programmable functions accessed
through a serial control channel that easily interfaces to
any classical micro controller. This IP Core is suitable
for digital mobile phones, as cellular and cordless
phones, or any battery powered equipment.
FEATURES
Analog 2.5Volt / Digital 1.8Volt Operation
Linear 14bit Codec
3 Mic Inputs (2 Differrential and 1 Single)
3 Analog Ouptuts 32ohm Driver (2 Differrential
and 1 Single)
Mic Volume 0dB ~ 22.5dB & 20dB Gain On/Off
Speaker Volume 0dB ~ -30dB
Sidetone -12.5dB ~ -27.5dB
Serial Data Input, Output Format
Control Register Interface for
μ
