Phase-locked-loop with VCO
FEATURES Low power consumption Centre frequency of up to 17 MHz (typ.) at VCC = 4.5 V Choice of three phase comparators: EXCLUSIVE-OR; edge-triggered JK flip-flop; edge-triggered RS flip-flop Excellent VCO frequency linearity VCO-inhibit control for ON/OFF keying and for low standby power consumption Minimal frequency drift Operating power supply voltage range: VCO section 3.0 to 6.0 V digital section 2.0 to 6.0 V Zero voltage offset due to op-amp buffering Output capability: standard ICC category: MSI. GENERAL DESCRIPTION Phase comparators The 74HC/HCT4046A are high-speed Si-gate CMOS devices and are pin compatible with the “4046” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4046A are phase-locked-loop circuits that comprise a linear voltage-controlled oscillator (VCO) and three different phase comparators (PC1, PC2 and PC3) with a common signal input amplifier and a common comparator input. The signal input can be directly coupled to large voltage signals, or……
