Description
Common-Mode Reference Voltage for the Differential Amplifier’s Output Voltage Swing. Internally biased to
three-fifths of V
Differential Amplifier Output to Tune the External VCO.
Fast-Lock Switch 3. Closed while SW3 timeout counter is active.
Analog Ground. This is the ground return pin for the differential amplifier and the RF section.
Complementary Input to the RF Prescaler. This point must be decoupled to the ground plane with a small bypass
capacitor, typically 100 pF.
Input to the RF Prescaler. This small signal input is ac-coupled to the external VCO.
Power Supply Pin for the RF Section. Nominally 3 V. A 100 pF decoupling capacitor to the ground plane should be
placed as close as possible to this pin.
Power Supply Pin for the N Divider. Should be the same voltage as AV
should be placed as close as possible to this pin.
Ground Return Pin for DV
Power Supply Pin for the REF
should be placed as close as possible to this pin.
Reference Input. This is a CMOS input with a nominal threshold of V
100 kΩ (see Figure 15). This input can be driven from a TTL or CMOS crystal oscillator or it can be ac-coupled.
Ground Return Pin for DV
Power Supply Pin for the Serial Interface Logic. Nominally 3 V.
Ground Return Pin for the Σ-Δ Modulator.
Power Supply Pin for the Digital Σ-Δ Modulator. Nominally 3 V. A 0.1 μF decoupling capacitor to the ground plane
should be placed as close as possible to this pin.
Multiplexer Output. This multiplexer output allows either the lock detect, the scaled RF, or the scaled reference
frequency to be accessed externally (see Figure 35).
Serial Clock Input. Data is clocked 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 three LSBs as 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 register is loaded into the register that is
selected by the three LSBs.
Power Supply Pin for the Phase Frequency Detector (PFD). Nominally 5 V, should be at the same voltage at V
A 0.1 μF decoupling capacitor to ground should be placed as close as possible to this pin.
