SEMICONDUCTOR TECHNICAL DATA  
Technical Summary  
P SUFFIX  
PLASTIC DIP  
CASE 710  
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 microcom-  
puter 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 Recommen-  
dation G.726. This device also meets the PCM conformance specification of the  
CCITT G.714 Recommendation.
