IDT821064 QUAD PROGRAMMABLE PCM CODEC WITH GCI INTERFACE

INDUSTRIAL TEMPERATURE RANGE

signaling pins to SLIC on per channel basis.

DESCRIPTION

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.

The IDT821064 is a feature rich, single-chip, programmable 4 chan-

nel PCM CODEC with on-chip filters. Besides the m-Law/A-Law

companding and linear coding/decoding (14 effective bits + 2 extra sign

bits), IDT821064alsoprovides1FSKgenerator(canbeusedforsending

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
