. VCP
S
can be set as high as 5.5 V for
VCOs requiring extended tuning range.

CP
Charge Pump Output.
10 CLK2
Clock Input Used to Connect External VCO/VCXO to Feedback Divider, N. CLK2 also drives the distribution
section of the chip and can be used as a generic clock input when PLL is not used.
11 CLK2B Complementary Clock Input Used in Conjunction with CLK2.
14 CLK1 Clock Input that Drives Distribution Section of the Chip.
15 CLK1B Complementary Clock Input Used in Conjunction with CLK1.
16 FUNCTION
Multipurpose Input Can Be Programmed as a Reset (RESETB), Sync (SYNCB), or Power-Down (PDB) Pin. This
pin is internally pulled down by a 30 kΩ resistor. If this pin is left NC, the part is in reset by default. To avoid
this, connect this pin to V
S
with a 1 kΩ resistor.
17 STATUS Output Used to Monitor PLL Status and Sync Status.
18 SCLK Serial Data Clock.
19
SDIO
Serial Data I/O.
20 SDO Serial Data Output.
21 CSB Serial Port Chip Select.
24 OUT7B Complementary LVDS/Inverted CMOS Output.
25 OUT7 LVDS/CMOS Output.
05046-003
NOTES
1. THE EXPOSED PADDLE ON THIS PACKAGE IS AN ELECTRICAL CONNECTION AS
WELL AS A THERMAL ENHANCEMENT. FOR THE DEVICE TO FUNCTION PROPERLY,
THE PADDLE MUST BE ATTACHED TO GROUND, GND.
