TI Delivers Industry"s First Stereo Audio CODEC With Built-In USB Controller And S/PDIF I/O Terminal
Audio CODEC From TI's Burr-Brown Product Line Saves Space and Cost
TOKYO, March 6 /PRNewswire/ -- Providing a high-performance audio solution
for the home entertainment market, Texas Instruments (NYSE: TXN - news; TI) unveiled
the industry's first stereo audio CODEC family with a built-in USB controller
and an internal S/PDIF-compatible I/O terminal.
Addressing the consumer's
need to download and edit digital audio material on PCs as well as transmit
the data to audio equipment, the family is ideal for mini-stereo decks,
portable CD/cassette radios, headphone/microphone combo units and domestic-use
robots.

"TI's PCM290x series adds more value to audio equipment by integrating USB
functions while reducing size and cost by 50 percent compared with existing
USB controllers with S/PDIF functionality," said Yuzo Sugiki, marketing
manager, TI Digital Audio.
"The series can be applied to a wide range of
digital consumer appliances, which will help us serve our customers more
effectively."
The PCM290x family includes four products with two different power supply
formats, the USB bus-powered PCM2900 and PCM2902 with an operating voltage of
2.7-3.6V, and the self-powered PCM2901 and PCM2903 with an operating voltage
of 5V.
With a 16-bit resolution and maximum sample rate of 48KHz, the
PCM290x family has a dynamic range of 89dB (typ) for analog-to-digital
converters and 93dB (typ) for digital-to-analog converters with 0.005 percent
THD+N (typ) in self-powered products.
In addition, the PCM290x series contains built-in protection against
unauthorized copying (SCMS), is full duplex compatible with a 12 MHz on-chip
clock generator and features HID (human interface device), volume and mute
control.
The series also contains a suspend flag feature that saves power in
target applications, notifying external circuits to the condition of the PC
suspending.
The PCM290x series has consolidated the USB device disk repeater function,
normally controlled by a microcomputer, onto a single chip, making it possible
to reduce the board surface area by 50 percent.
Furthermore, the product is
controlled by the USB drivers included in the OS software, eliminating the
need for specialized drivers and making product development more efficient.
The product series also uses TI's Sampling Period Adaptive Controlled
Tracking System (SpAct)(TM), which enables the splitting of a single clock
source using a PLL circuit.
In addition, the series is compatible with
multiple sampling rates and suppresses jitter to extremely low levels.
