Pin Description

VD

1

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

GND

2

Ground (Input) - Ground reference.

CLK_OUT

3

PLL Clock Output (Output) - PLL clock output.

AUX_OUT

4

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.

TST_IN

5

Test Input (Input) - This pin is for factory test purposes and must be connected to GND for proper

operation.

XTO

XTI/REF_CLK

6

7

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.

AD0/CS

8

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.

SCL/CCLK

9

Control Port Clock (Input) - SCL/CCLK is the serial clock for the serial control port in I²C and SPI

mode.

SDA/CDIN

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.
