IDT821064 QUAD PROGRAMMABLE PCM CODEC WITH GCI INTERFACE
DESCRIPTION
The IDT821064 is a feature rich, single-chip, programmable 4 chan-
nel PCM CODEC with on-chip filters. Besides the
μ
-Law/A-Law
companding and linear coding/decoding (14 effective bits + 2 extra sign
bits), IDT821064 also provides 1 FSK generator (can be used for sending
Caller-ID messages), 2 programmable Tone generators per channel
(which can also generate ring signals) together with 2 programmable
chopper clocks for SLIC.
The digital filters in IDT821064 provide the necessary transmit and
receive filtering for voice telephone circuit to interface with time-division
multiplexed systems. An integrated programmable DSP realizes AC
Impedance Matching, Transhybrid Balance, Frequency Response
Correction and Gain Setting functions. The device also provides 7
PIN CONFIGURATIONS
signaling pins to SLIC on per channel basis.
The IDT821064 has a General Control Interface (GCI), which is also
known as ISDN Oriented Module (IOM
-2). The IDT821064 supports
both compressed and linear data format. This function provides
convenience for the VoXXX applications.
The device also offers strong test capability with several analog/digital
loopbacks and level metering function. It brings convenience to system
maintenance and diagnosis.
A unique feature of ‘Hardware Ring Trip’ is implemented in IDT821064.
When off-hook signal is detected, IDT821064 can reverse an output pin
to stop ringing immediately.
The IDT821064 can be used in Integrated Access Devices (IADs), i.e.
VoIP and VoDSL.
