Product Description

The CJC8911 is a low power, high quality Mono CODEC designed for portable digital audio applications.
The device integrates complete interfaces to ONE line out ports. Advanced on-chip digital signal processing performs graphic equalizer, 3-D sound enhancement and automatic level control for the microphone or line input.

The CJC8911 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 CJC8911 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 3.3Volts. Different sections of the chip can also be powered down under software control. The CJC8911 is supplied in a very small and thin 4x4mm COL package, ideal for use in hand-held and portable systems.
