SRC4190中文资料192kHz 立体声异步采样速率转换器数据手册TI规格书

描述 Description

The SRC4190 device is an asynchronous sample rate converter designed for professional and broadcast audio applications. The SRC4190 combines a wide input-to-output sampling ratio with outstanding dynamic range and low distortion. Input and output serial ports support standard audio formats, as well as a Time Division Multiplexed (TDM) mode. Flexible audio interfaces allow the SRC4190 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors.
The SRC4190 is a standalone pin-programmed device, with control pins for mode, data format, mute, bypass, and low group delay functions.
The SRC4190 may be operated from a single 3.3-V power supply. A separate digital I/O supply (VIO) operates with a 1.65-V to 3.6-V supply, allowing greater flexibility when interfacing to current and future generation signal processors and logic devices. The SRC4190 is available in a 28-pin SSOP package.
