T8502 General Description

The T8502 and T8503 devices are single-chip, twochannel, m-law/A-law PCM codecs with filters. These integrated circuits provide analog-to-digital and digital-to-analog conversion. They provide the transmit and receive filtering necessary to interface a voice telephone circuit to a time-division multiplexed system. These devices are packaged in both 20-pin SOJs and 20-pin SOGs.

The T8502 differs from the T8503 in its timing mode. The T8502 operates in the delayed timing mode (digital data is valid one clock cycle after frame sync goes high), and the T8503 operates in the nondelayed timing mode (digital data valid when frame sync goes high) (see Figures 5 and 6).
