TI's Sample Rate Converters Offer Highest Performance for Industry

7/11/2003 - Texas Instruments (TI) Incorporated (NYSE: TXN) introduced the industry´s highest performance sample rate converters from the company´s Burr-Brown Pro Audio product line. Featuring 144dB dynamic range and -140dB distortion, the devices are ideal for a variety of professional audio applications, such as digital mixing consoles, digital audio workstations, audio distribution, high-end A/V receivers and broadcast studio equipment.

"We are excited to bring to market the world's highest performance sample rate converter. The SRC4192/3 achieves a level of performance that will allow sample rate conversion to be transparent in the audio signal path, which is ideal for pro audio systems," said Mike Centorino, marketing manager for TI's Burr-Brown Pro Audio products.

The SRC4192/3 combines a wide input-to-output sampling ratio (handling all major audio rates up to 212kHz) with outstanding dynamic range (144dB) and ultra-low distortion (-140dB THD+N). Input and output serial ports support standard audio formats. The flexible audio interfaces allow the SRC4192/3 to connect to a wide range of audio data converters, digital audio receivers/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), which is utilized to program all functions via internal control registers. A lower-cost, pin-compatible device, the SRC4190, is also available with 128dB dynamic range and -125dB THD+N.

All three devices can be operated from a single +3.3V power supply. A separate digital I/O supply operates over the +1.65V to +3.6V supply range, providing greater flexibility when interfacing to current and future generation signal processors and logic devices.
