whose current is set by an external
resistor R
b
Centre frequency tolerance
±
10%
Excellent
voltage-controlled-oscillator (VCO)
linearity
Low frequency drift with supply
voltage and temperature variations
On chip bandgap reference
Glitch free operation of VCO, even
at very low frequencies
Inhibit control for ON/OFF keying
and for low standby power
consumption
Operation power supply voltage

APPLICATIONS
FM modulation and demodulation
where a small centre frequency
tolerance is essential
Frequency synthesis and
multiplication where a low jitter is
required (e.g. Video
picture-in-picture)
Frequency discrimination
(1) R
