Additional AES3/SPDIF Receiver Port
(
Input
) - Single-ended receiver inputs carrying AES3 or
S/PDIF digital data. These inputs comprise the 8:2 S/PDIF Input Multiplexer. The select line control is
accessed using the Control 4 register. Please note that any unused inputs can be left floating or tied to
ground. See Appendix A for recommended input circuits.
RXN
AES/SPDIF input
- Used along with RXP[X] to form an AES3 differential input. In single-ended
operation this should be capacitively coupled to ground.
Positive Analog Power
- Positive supply for the analog section. Nominally +3.3 V. This supply should
be as quiet as possible since noise on this pin will directly affect the jitter performance of the recovered
clock
Positive Digital Power
鈥?Nominally 3.3 V
Positive 鈥?Interface Power
鈥?3.3 V to 5.0 V: this supply sets the CS8416 I/O levels, including RXPx &
RXN
Analog Ground
- Ground for the analog circuitry in the chip. AGND and DGND should be con nected
to a common ground area under the chip.
Digital & I/O Ground
PLL Loop Filter
(
Output
) - An RC network should be connected between this pin and analog ground.
For minimum PLL jitter, return the ground end of the filter network directly to AGND
