Pin Descriptions
PIN #
PIN NAME
PIN TYPE
DESCRIPTION
1
AVDD2.5
PWR
2.5V Analog Power pin for Core PLL
2
AGND
PWR
Analog Ground pin for Core PLL
3IREFY
IN
This pin establishes the reference current for the differential clock
pairs. This pin requires a fixed precision resistor tied to ground in
order to establish the appropriate current.

AGND
PWR
Analog Ground pin for Core PLL
5
CLK_INT
IN
"True" reference clock input.
6
CLK_INC
IN
"Complementary" reference clock input.
7
VDD2.5
PWR
Power supply, nominal 2.5V
8
GND
PWR
Ground pin.

SMBus address bit 0 (LSB)
13
SMB_A1
IN
SMBus address bit 1
14
BYPASS#/PLL
IN
Input to select Bypass(fan-out) or PLL (ZDB) mode
0 = Bypass mode, 1= PLL mode
