FUNCTION
Analog Input
Supply Pin
Analog
Input/Output
VCO tuning voltage input
Ground
Regulated voltage output to supply the VCO.
Bypass with a 0.01µF capacitor to GND as
close to the part as possible.
Supply Pin
Power supply pin for VCO circuits. Bypass
with a 1000pF and a 10µF capacitor to GND
as close to the part as possible.
Analog Input Resistor to ground on this pin sets the
Resistor to Ground modulation filter bandwidth.
Digital Input
Chip-enable digital input pin. Set EN low
maintain the chip in power-down mode.
Digital Input
Digital Input
Digital Input
Enable for crystal oscillator and frequency
reference buffer.
BPSK modulation input
On-off keying modulation. On state = high.
Supply
Power supply pin for internal RF buffer
circuits. Bypass with a 100pF and a 0.01µF
capacitor to GND as close to the part as
possible.
Analog Voltage
Input
ASK voltage input pin
Digital Output
Lock detector output digital pin. Level is
high when PLL is inside lock range.
Do NOT Connect —
Analog Input Current input set to adjust output power.
Resistor to Ground
Supply
Power supply pin for RF power amplifier
circuits. Bypass with a 100pF capacitor to GND
as close to the part as possible.
