Product specification
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 by an external resistor Rb • Centre frequency tolerance ±10% • Excellent
voltage-controlled-oscillator (VCO) linearity • Low frequency drift with supply
voltage and temperature variations • O...
