Low power consumption
Centre frequency up to
17 MHz (typ.) at V
Choice of two phase
comparators
– EXCLUSIVE-OR (PC1)
– Edge-triggered JK flip-flop (PC2)
No dead zone of PC2
Charge pump output on PC2,
whose current is set by an external
resistor R
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
range 4.5 to 5.5 V
Zero voltage offset due to op-amp
buffering
Output capability: standard

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
