T8503规格书详情
Description
The T8502 and T8503 devices are single-chip, two channel, µ-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.
Features
■ +5 V only
■ Two independent channels
■ Pin-selectable receive gain control
■ Pin-selectable µ-law or A-law companding
■ Automatic powerdown mode
■ Low-power, latch-up-free CMOS technology
— 40 mW/channel typical operating power dissipation
— 12.5 mW/channel typical standby power dissipation
■ Automatic master clock frequency selection
— 2.048 MHz or 4.096 MHz
■ Independent transmit and receive frame strobes
■ 2.048 MHz or 4.096 MHz data rate
■ On-chip sample and hold, autozero, and precision voltage reference
■ Differential architecture for high noise immunity and power supply rejection
■ Meets or exceeds ITU-T G.711—G.714 require ments and VF characteristics of D3/D4 (as per Bellcore PUB43801)
■ Operating temperature range: –40 °C to +85 °C
