VDD  
(Note 1)  
Power supply input. Input may range from 2.85 V to 3.15 V. Bypassing required.  
Enhancement mode. When asserted low (“0”), enhancement register bits are functional. Internal 70 kΩ  
pull-up resistor.  
Enh  
Input  
Serial load enable input. While S_WR is “low”, Sdata can be serially clocked. Primary register data are  
transferred to the secondary register on S_WR rising edge.

Input  
Input  
Binary serial data input. Input data entered MSB first.  
Serial clock input. Sdata is clocked serially into the 20-bit primary register (E_WR “low”) or the 8-bit  
enhancement register (E_WR “high”) on the rising edge of Sclk.  
GND  
Ground.  
Selects contents of primary register (FSELS=1) or secondary register (FSELS=0) for programming of internal  
counters. Internal 70 kpull-down resistor.  
FSELS

Enhancement register write enable. While E_WR is “high”, Sdata can be serially clocked into the  
enhancement register on the rising edge of Sclk. Internal 70 kpull-down resistor.

Prescaler input from the VCO. Max frequency input is 2.2 GHz.  
Prescaler complementary input. A bypass capacitor should be placed as close as possible to this pin and be  
connected in series with a 50 resistor to the ground plane.

Input  
GND  
Cext  
Ground.  
Logical “NAND” of PD_U and PD_D terminated through an on chip, 2 kseries resistor. Connecting Cext to  
an external capacitor will low pass filter the input to the inverting amplifier used for driving LD.  
Output  
Output  
Lock detect is an open drain logical inversion of CEXT. When the loop is in lock, LD is high impedance,  
otherwise LD is a logic low (“0”).
