TI Delivers Combo Sample Rate Converter For Pro Audio Applications
Texas Instruments Incorporated 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 combines a wide input-to-output sampling ratio, handling all major audio rates up to 216kHz, with dynamic range of 144dB and distortion of -140dB THD+N. SPI or I2C interface provides access to on-chip registers and data buffers.
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.
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).
