Description
Connecting a resistor between this pin and CPGND sets the maximum charge pump output current. The
nominal voltage potential at the R
so, with R
Charge Pump Output. When enabled, this pin provides ±I
the external VCO.
Charge Pump Ground. This is the ground return path for the charge pump.
Analog Ground. This is the ground return path of the prescaler.
Complementary Input to the RF Prescaler. This point must be decoupled to the ground plane with a small
bypass capacitor, typically 100 pF. See Figure 18.
Input to the RF Prescaler. This small signal input is ac-coupled to the external VCO.
Analog Power Supply. This voltage may range from 2.7 V to 3.3 V. Decoupling capacitors to the analog
ground plane should be placed as close as possible to this pin. AV
Reference Input. This is a CMOS input with a nominal threshold of V
resistance of 100 kΩ. See Figure 17. This input can be driven from a TTL or CMOS crystal oscillator or it can
be ac-coupled.
Digital Ground.
Chip Enable. A logic low on this pin powers down the device and puts the charge pump output into three-
state mode. Taking the pin high powers up the device, depending on the status of the power-down bit, F2.
Serial Clock Input. This serial clock is used to clock in the serial data to the registers. The data is latched
into the 24-bit shift register on the CLK rising edge. This input is a high impedance CMOS input.
Serial Data Input. The serial data is loaded MSB first with the two LSBs being the control bits. This input is a
high impedance CMOS input.
Load Enable, CMOS Input. When LE goes high, the data stored in the shift registers is loaded into one of
the four latches, the latch being selected using the control bits.
This multiplexer output allows either the lock detect, the scaled RF, or the scaled reference frequency to
be accessed externally.
Digital Power Supply. This may range from 2.7 V to 3.3 V. Decoupling capacitors to the digital ground
plane should be placed as close as possible to this pin. DV
Charge Pump Power Supply. This voltage should be greater than or equal to V
can be set to 5 V and used to drive a VCO with a tuning range of up to 5 V.
