The 92HD66C provide stereo 24- bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. SPDIF outputs support sample rates of 192kHz, 96kHz, 88.2kHz, 48kHz, and
44.1kHz. SPDIF input supports 96KHz, 88.2KHz, 48KHz, and 44.1KHz sample rates. Additional
sample rates are supported by the driver software.
The 92HD66C supports a wide range of desktop and laptop 6-channel configurations. The 2 inde-
pendent SPDIF output interfaces provides connectivity to consumer electronic equipment or to a
home entertainment system. Simultaneous HDMI and SPDIF output is possible. All inputs can be
programmed with 0-30 dB gain in 10 dB steps allowing for line or microphone use of any input.
Port presence detect capabilities allow the CODEC to detect when audio devices are connected to
the CODEC. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion and
removal for protection of notebook speakers.
The 92HD66C operates with a 3.3V digital supply and a 5V analog supply. It allows for 1.5V and
3.3V HDA signaling; the correct signalling level is selected based on the power supply voltage on the
DVDD-IO pin.
The 92HD66C is offered in a 48 or 40 pin QFN Environmental (ROHS) package.
Add an “8” to the end for tape and reel delivery.
