Analog Power (Input) - Analog power supply. Nominally +3.3 V. This supply should have as little
noise as possible since noise on this pin will directly affect the jitter performance of the recovered
clock
Digital Power (Input) – Digital core power supply. Nominally +3.3 V
Logic Power (Input) – Input/Output power supply. Nominally +3.3 V or +5.0 V
Analog Ground (Input) - Ground for the analog circuitry in the chip. AGND and DGND should be
connected to a common ground area under the chip.
Digital & I/O Ground (Input) - Ground for the I/O and core logic. AGND and DGND should be con-
nected to a common ground area under the chip.
Reset (Input) - When RST is low, the CS8416 enters a low power mode and all internal states are
reset. On initial power up, RST must be held low until the power supply is stable, and all input clocks
are stable in frequency and phase.
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. See
on page 53
Positive AES3/SPDIF Input (Input) - Single-ended or differential receiver inputs carrying AES3 or
S/PDIF encoded digital data. The RXP[3:0] inputs comprise the 4:2 S/PDIF Input Multiplexer. The
select line control is accessed using the RXPSEL[1:0] pins. Unused multiplexer inputs should be left
floating or tied to AGND. See
for recommended input circuits.
