Pin Description

Digital Power

(Input) - Positive power supply for the digital and analog sections.

Ground

(Input) - Ground reference.

PLL Clock Output

(Output) - PLL clock output.

Auxiliary Output

(Output) - This pin outputs a buffered version of one of the input or output clocks,

or a status signal, depending on register configuration.

Frequency Reference Clock Input

(Input) - Clock input for the Digital PLL frequency reference.

Crystal Connections (XTI/XTO) / Timing Reference Clock Input (REF_CLK)

(Input/Output) -

XTI/XTO are I/O pins for an external crystal which may be used to generate the low-jitter PLL input

clock. REF_CLK is an input for an externally generated low-jitter reference clock.

Address Bit 0 (I²C) / Control Port Chip Select (SPI)

(Input) - AD0 is a chip address pin in I²C

Mode. CS is the chip select signal in SPI Mode.

Control Port Clock

(Input)

- SCL/CCLK is the serial clock for the serial control port in I²C and SPI

mode.

10

Serial Control Data

(Input/Output) - SDA is the data I/O line in I²C Mode. CDIN is the input data

line for the control port interface in SPI Mode.
