IDT821054 QUAD PROGRAMMABLE PCM CODEC WITH MPI INTERFACE
INDUSTRIAL TEMPERATURE RANGE
DESCRIPTION
The IDT821054 is a feature rich, single-chip, programmable 4-
channel PCM CODEC with on-chip filters. Besides the µ-Law/A-Law
companding and linear coding/decoding (14 effective bits + 2 extra sign
bits), the IDT821054 also provides 1 FSK generator for sending Caller-
ID messages, 2 programmable tone generators per channel (which can
generate ring signals) and 2 programmable chopper clocks for SLICs.
The digital filters in the IDT821054 provide necessary transmit and
receive filtering for voice telephone circuits to interface with time-division
multiplexed systems. An integrated programmable DSP realizes AC
impedance matching, transhybrid balance, frequency response
correction and gain adjustment functions. The IDT821054 supports 2
PCM buses with programmable sampling edge, which allows an extra
delay of up to 7 clocks. Once the delay is determined, it is effective to all
four channels of the IDT821054. The device also provides 7 signaling
pins per channel for SLICs.
The IDT821054 is programmed via a Microprocessor Interface (MPI).
Two PCM buses are provided to transfer the compressed or linear PCM
data.
The device 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 the
IDT821054. When an off-hook signal is detected, the IDT821054 will
reverse an output pin to stop the ringing signal immediately.
The IDT821054 can be used in digital telecommunication
applications such as Central Office Switch, PBX, DLC and Integrated
Access Devices (IADs), i.e. VoIP and VoDSL.
