Descriptions
Charge Pump Ground. This is the ground return path for the charge pump.
Analog Power Supply. This ranges from 3.0 V to 3.6 V. Decoupling capacitors to the analog ground plane
should be placed as close as possible to this pin. AV
Analog Ground. This is the ground return path of the prescaler and VCO.
VCO Output. The output level is programmable from −6 dBm to −13 dBm. See the Output Matching section
for a description of the various output stages.
VCO Complementary Output. The output level is programmable from −6 dBm to −13 dBm. See the
Output Matching section for a description of the various output stages.
Power Supply for the VCO. This ranges from 3.0 V to 3.6 V. Decoupling capacitors to the analog ground plane
should be placed as close as possible to this pin. V
Control Input to the VCO. This voltage determines the output frequency and is derived from filtering the CP
output voltage.
Internal Compensation Node. This pin must be decoupled to ground with a 10 nF capacitor.
Connecting a resistor between this pin and CP
synthesizer. The nominal voltage potential at the R
where R
Internal Compensation Node. This pin must be decoupled to V
Digital Ground.
Reference Input. This is a CMOS input with a nominal threshold of V
100 kΩ. See Figure 10. This input can be driven from a TTL or CMOS crystal oscillator, or it can be ac-coupled.
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, and the relevant latch is 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 ranges from 3.0 V to 3.6 V. Decoupling capacitors to the digital ground plane
should be placed as close as possible to this pin. DV
Chip Enable. A logic low on this pin powers down the device and puts the charge pump into three-state
mode. Taking the pin high powers up the device depending on the status of the power-down bits.
Charge Pump Output. When enabled, this provides ± I
internal VCO.
