TI Delivers Highest Performance Combo Sample Rate Converter for Professional Audio Applications

Device Integrates SRC with Digital Audio Interface Receiver and Transmitter

Nov 10, 2006

DALLAS (Nov. 10, 2006) -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's highest performance, combo sample rate converter (SRC) from the company's Burr-Brown pro audio product line. The SRC4392 integrates a two-channel asynchronous SRC with a digital audio interface receiver (DIR) and transmitter (DIT). Featuring 144dB dynamic range, -140dB distortion and up to 216kHz sampling rates, the device is used in a variety of professional and broadcast audio applications, such as digital mixing consoles, digital audio workstations, audio distribution and broadcast studio equipment.

"The SRC4392 delivers performance and integration that is unmatched in the market," said Mike Centorino, marketing manager for TI's Burr-Brown Pro Audio products. "No other integrated sample rate converter provides customers with 192kHz sampling rates and 144dB dynamic range in a single chip. This device enables digital audio recovery and sample rate conversion to be transparent in the audio signal path, which is ideal for pro audio systems."
The SRC4392 combines a wide input-to-output sampling ratio, handling all major audio rates up to 216kHz, with outstanding dynamic range of 144dB and ultra-low distortion of -140dB THD+N. SPI or I2C interface provides access to on-chip registers and data buffers.
The SRC4392 is part of TI's broad portfolio of signal chain solutions for pro audio applications, including high-performance audio data converters (ADCs and DACs), digital amplifier power stages, audio op amps, microphone preamplifiers, volume controls and digital signal processors (DSPs).
The SRC43x2 family includes a lower-cost, pin-compatible device, the SRC4382, with 128dB dynamic range and -125dB THD+N. Both devices operate from a +1.8V core supply and a +3.3V digital I/O supply.

Availability and Packaging

The SRC4392 and SRC4382 are available now from TI and its authorized distributors in small 48-lead TQFP packages. The SRC4392 is priced at $9.95 in 1,000-piece quantities; the SCR4382 is priced at $7.50 in 1,000-piece quantities (suggested resale pricing).
