3. EXTENDED FEATURE EXPLANATION
3.1.
SPDIF Input
SPDIF IN can run at 44.1 KHz, 48 KHz and 96 KHz, and has internal Jack Sensing.
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.
Advanced features such as record slot select and SPDIF_IN routing to the DAC allows for simulta-
neous record and play.
3.2.
SPDIF Output
SPDIF Output can run at 44.1 KHz, 48 KHz, and 96 KHz at bit rates up to 24 bits, as defined in the
Intel High Definition Audio Specification. This insures compatibility with all consumer audio gear and
allows for convenient integration into home theater systems and multi-media centers.
3.3.
Universal JacksTM
IDT’s Universal JacksTM technology allows for the greatest flexibility in board design and implemen-
tation.
For the 92HD001 the Universal JacksTM capabilities are as follows
All of the 92HD001 ports support:
Line Out
Line In
Mic with 0/10/20/30/40 dB Mic Boost
Ports A and D also support
Headphone Out1
1Headphone capabilities are available on pins 39/41 and 35/36, but one should not put headphone
loads on both sets of pins at the same time.
Note: On the 92HD001 only one function can be selected at a time, you cannot have an input
and output at the same time on the same set of pins. This function can be changed at any time.
3.4.
Audio Jack Presence Detect
Sense_A pin is used to detect the presence of plugs in ports A, B, C, and D. Refer to the reference
design for port detect circuitry. Select the precision of the resistors used as follows:
Includes pull-up resistors on Sense A and series resistors between jack switch and Sense A.
