Conforms to G.721–1988 and T1.301–1987
The MC145532 Adaptive Differential Pulse Code Modulation (ADPCM)
Transcoder provides a low–cost, full–duplex, single–channel transcoder to
(from) a 64 kbps PCM channel from (to) either a 16 kbps, 24 kbps, 32 kbps, or
64 kbps channel.
Complies with CCITT Recommendation G.721–1988
Complies with the American National Standard (T1.301–1987)
Full–Duplex, Single–Channel Operation
Mu–Law or A–Law Coding is Pin Selectable
Synchronous or Asynchronous Operation
Easily Interfaces with Any Member of Motorola’s PCM Codec–Filter
Mono–Circuit Family or Other Industry Standard Codec
Serial PCM and ADPCM Data Transfer Rate from 64 kbps to 5.12 Mbps
Power–Down Capability for Low Current Consumption
The Reset State, an Option Specified in the Standards, is Automatically
Initiated When the RESET Pin is Released
Simple Time Slot Assignment Timing for Transcoder Applications
Single 5 V Power Supply
16–Pin Package
The MC145536EVK is the Evaluation Platform for the MC145532 and Also
Includes the MC145480 5 V PCM Codec–Filter
