Description
Connecting a resistor between R
The relationship between I
where R
Charge Pump Output. When enabled, CP provides ±I
drives 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 pin should be decoupled to the ground plane
with a small bypass capacitor, typically 100 pF (see Figure 12).
Input to the RF Prescaler. This small signal input is normally ac-coupled from the VCO.
Positive Power Supply for the RF Section. Decoupling capacitors to the digital ground plane should
be placed as close as possible to this pin. AV
voltage as DV
Reference Input. This is a CMOS input with a nominal threshold of V
resistance of 100 kΩ (see Figure 11). This input can be driven from a TTL or CMOS crystal oscillator,
or it can be ac-coupled.
Digital Ground.
Σ-Δ Power. Decoupling capacitors to the digital ground plane should be placed as close as possible
to this pin. SDV
Serial Clock Input. The serial clock is used to clock in the serial data to the registers. The data is
latched into the 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; the two LSBs are the control bits. This input is
a high impedance CMOS input.
Load Enable, CMOS Input. When LE is high, the data stored in the shift registers is loaded into one
of four latches; the latch is selected using the control bits.
This multiplexer output allows either the RF lock detect, the scaled RF, or the scaled reference
frequency to be externally accessed.
Positive Power Supply for the Digital Section. Decoupling capacitors to the digital ground plane
should be placed as close as possible to this pin. DV
the same voltage as AV
Charge Pump Power Supply. This should be greater than or equal to V
it can be set to 5.5 V and used to drive a VCO with a tuning range of up to 5.5 V.
