Description: PLL with bandgap controlled VCO

Features

* Low power consumption
* Centre frequency up to 17 MHz (typ. ) at VCC = 5.5 V
* Choice of two phase comparators(1):
* EXCLUSIVE-OR (PC1)
* Edge-triggered JK flip-flop (PC2)
* No dead zone of PC2
* Charge pump output on PC2, whose current is set

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) Rb connected between pin 15 and ground: PC2 mode, with
