92HD65C
SIX CHANNEL HD AUDIO CODEC WITH DUAL CAPLESS HEADPHONE AMPLIFIERS
1. DESCRIPTION
1.1. Overview
The 92HD65C 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 92HD65C 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 92HD65C operates with a 3.3V digital supply and a 5V analog supply. It allows for 3.3V HDA
signaling.
The 92HD65C is offered in a 40 pin QFN Environmental (ROHS) package.
