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.
Power supply pin for VCO circuits. Bypass
with a 1000pF and a 10µF capacitor to GND
as close to the part as possible.
Resistor to ground on this pin sets the
modulation filter bandwidth.
Chip-enable digital input pin. Set EN low
maintain the chip in power-down mode.
Enable for crystal oscillator and frequency
reference buffer.
BPSK modulation input
On-off keying modulation. On state = high.
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.
ASK voltage input pin
Lock detector output digital pin. Level is
high when PLL is inside lock range.
Current input set to adjust output power.
