ADPCM Codec
**This technical summary provides a brief description of the MC14LC5540
ADPCM Codec. A complete data book for the MC14LC5540 is available and can be ordered from your local Motorola sales office. The data book number is MC145540/D.**
The MC14LC5540 ADPCM Codec is a single chip implementation of a PCM
Codec–Filter and an ADPCM encoder/decoder, and therefore provides an efficient
solution for applications requiring the digitization and compression of
voiceband signals. This device is designed to operate over a wide voltage
range, 2.7 to 5.25V and, as such, is ideal for battery powered as well as ac
powered applications. The MC14LC5540 ADPCM Codec also includes a serial
control port and internal control and status registers that permit a
microcomputer to exercise many built–in features.
The ADPCM Codec is designed to meet the 32 kbps ADPCM conformance requirements
of CCITT Recommendation G.721–1988 and ANSI T1.301. It also meets ANSI T1.303
and CCITT Recommendation G.723–1988 for 24 kbps ADPCM operation, and the 16
kbps ADPCM standard, CCITT Recommendation G.726. This device also meets the
PCM conformance specification of the CCITT G.714 Recommendation.
