The is a low power, high quality stereo CODEC designed for portable digital audio
applications.
The device integrates complete interfaces to 2 stereo headphone or line out ports. External
component requirements are drastically reduced as no separate headphone amplifiers are
required. Advanced on-chip digital signal processing performs graphic equaliser, 3-D sound
enhancement and automatic level control for the microphone or line input.
The can operate as a master or a slave, with various master clock frequencies
including 12 or 24MHz for USB devices, or standard 256fs rates like 12.288MHz and
24.576MHz. Different audio sample rates such as 96KHz, 48KHz, 44.1KHz are generated
directly from the master clock without the need for an external PLL.
The operates at supply voltages down to 1.8V, although the digital core can operate at
voltages down to 1.5V to save power, and the maximum for all supplies is 3Volts. Different
sections of the chip can also be powered down under software control. The is supplied
in a very small and thin 4x4mm COL package, ideal for use in hand-held and portable systems.
