The SRC4192 and SRC4193 are asynchronous sample rate converters designed for professional and broadcast audio applications. The SRC4192 and SRC4193 combine a wide input-to-output sampling ratio with outstanding dynamic range and ultra low distortion. Input and output serial ports support standard audio formats, as well as a Time Division Multi- plexed (TDM) mode. Flexible audio interfaces allow the SRC4192 and SRC4193 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. The SRC4192 is a standalone pin programmed device, with control pins for mode, data format, mute, bypass, and low group delay functions. The SRC4193 is a software-controlled device featuring a serial peripheral interface (SPI) port, which is utilized to program all functions via internal control registers. The SRC4192 and SRC4193 may be operated from a single +3.3V power supply. A separate digital I/O supply (VIO) operates over the +1.65V to +3.6V supply range, allowing greater flexibility when interfacing to current and future gen- eration signal processors and logic devices. Both the SRC4192 and SRC4193 are available in a 28-lead SSOP package.
The SRC4192 and SRC4193 are asynchronous sample‑rate converters designed for professional audio and broadcast applications. They support a wide input‑to‑output sampling ratio (16:1 to 1:16), up to 212 kHz sampling rates, and provide 144 dB dynamic range with ultra‑low distortion. Features include automatic input‑output ratio sensing, flexible audio serial ports (master/slave, multiple data formats), low‑group‑delay and direct down‑sampling options, SPI control (SRC4193 only), and programmable digital output attenuation.
These devices operate from a single +3.3 V supply in a 28‑lead SSOP package and are pin‑compatible with the AD1896 (SRC4192). Typical applications are digital mixing consoles, audio workstations, broadcast studio equipment, high‑end A/V receivers, and general digital audio processing.
