MC14LC5540DW - Brand New MOTOROLA Interface - CODECs
-
Description
The MC14LC5540DW is an electronic component model categorized as an interface codec. It provides a single chip implementation of a PCM Codec–Filter and an ADPCM encoder/decoder, making it an efficient solution for applications that require the digitization and compression of voiceband signals. It is designed to operate over a wide voltage range of 2.7 to 5.25V, making it suitable for both battery-powered as well as ac powered applications. The MC14LC5540DW ADPCM Codec also includes a serial control port and internal control and status registers that permit a microcomputer to exercise many built-in features.
Specifications and features
The MC14LC5540DW ADPCM Codec is designed to meet the following standards:
- 32 kbps ADPCM conformance requirements of CCITT Recommendation G.721-1988 and ANSI T1.301
- 24 kbps ADPCM operation of ANSI T1.303 and CCITT Recommendation G.723-1988
- 16 kbps ADPCM standard of CCITT Recommendation G.726
- PCM conformance specification of the CCITT G.714 Recommendation
The device is equipped with a voltage-regulated charge pump to power the analog circuitry in low voltage applications. It has a low noise, high gain, three-terminal input operational amplifier for a microphone interface. It also has push-pull, 300Ω power drivers with external gain adjust for a receiver interface, and push-pull, 300Ω auxiliary output drivers for a ringer interface. The MC14LC5540DW ADPCM Codec has a programmable transmit gain, receive gain, and sidetone gain, and a universal programmable dual-tone generator. It also has a receive noise burst detect algorithm.
Application Scenarios
The MC14LC5540DW ADPCM Codec is ideal for applications that require the digitization and compression of voiceband signals. Its efficient solution is suitable for battery-powered as well as AC-powered applications. It can also be used in microcomputer-controlled applications since it has a serial control port and internal control and status registers.
