T7502 产品详情

Description
The T7502 device is a single-chip, two-channel A-law PCM codec with filters. This integrated circuit provides analog-to-digital and digital-to-analog conversion. It provides the transmit and receive filtering necessary to interface a voice telephone circuit to a time-division multiplexed (TDM) system. The device features a differential transmit amplifier, and the power receive amplifier is capable of driving 600 Ω differentially. PCM timing is defined by a single frame sync pulse. This device operates in a delayed timing mode (digital data is valid one clock cycle after frame sync goes high). The T7502 is packaged in a 20-pin SOJ.

Features
■ +5 V only
■ Automatic powerdown mode
■ Low-power, latch-up-free CMOS technology
■ On-chip sample and hold, autozero, and precision voltage reference
■ Differential architecture for high noise immunity and power supply rejection
■ Automatic master clock frequency selection
■ 2.048 MHz or 4.096 MHz fixed data rate
■ Frame sync controlled channel swapping
■ Differential analog I/O
■ 300 Ω output drivers
■ Operating temperature range: –40 °C to +85 °C
■ A-law companding

Applications
■ Speakerphone
■ Telephone answering device (TAD)
■ POTS for ISDN

关于 Agere Systems


Agere Systems was a semiconductor company that specialized in providing integrated circuits (ICs) for telecommunications and storage applications. The company was founded in 2000 as a spin-off from Lucent Technologies, and was headquartered in Allentown, Pennsylvania, USA.

Agere Systems' product portfolio included ICs for wireless communication, networking, and storage applications. These products were used in a wide range of devices, including mobile phones, routers, switches, and data storage devices.

Agere Systems was known for its innovation and expertise in advanced semiconductor technologies, such as copper-based interconnects and silicon germanium (SiGe) technology. The company also had a strong focus on research and development, and held numerous patents in semiconductor design and manufacturing.

In 2005, Agere Systems was acquired by LSI Corporation, which later became part of Avago Technologies. Today, the technology and products developed by Agere Systems continue to be used in a variety of telecommunications and storage applications.
