Ground Substrate. This is on the bottom of the package and must be grounded.
RF PLL charge pump output.
RF PLL analog ground.
RF PLL analog power supply.
RF PLL high frequency input pin.
RF PLL complementary high frequency input pin. Shunt to ground with a 100 pF
capacitor.
MICROWIRE Load Enable. High impedance CMOS input. Data stored in the shift
registers is loaded into the internal latches when LE goes HIGH
MICROWIRE Data. High impedance binary serial data input.
MICROWIRE Clock. High impedance CMOS Clock input. Data for the various counters is
clocked into the 24 bit shift register on the rising edge
Power supply for RF PLL digital circuitry.
Chip Enable control pin. Must be pulled high for normal operation.
Power supply for RF PLL digital circuitry.
Test frequency output / Lock Detect.
IF PLL high frequency input pin.
IF PLL analog power supply.
IF PLL digital ground.
IF PLL charge pump output
IF PLL power supply.
Buffered output of the OSCin signal.
Oscillator enable. When this is set to high, the OSCout pin is enabled regardless of the
state of other pins or register bits.
Reference Input.
This pin must be left open.
Power supply for RF PLL digital circuitry.
RF PLL Fastlock Output. Also functions as Programmable TRI-STATE CMOS output.
RF PLL analog power supply.
