74HCT7046A Overview
The 74HC/HCT7046 are high-speed Si-gate CMOS devices and are specified in pliance with JEDEC standard no. The 74HC/HCT7046 are phase-locked-loop circuits that prise a linear voltage-controlled oscillator (VCO) and two different phase parators (PC1 and PC2) with a mon signal input amplifier and a mon parator input. A lock detector is provided and this gives a HIGH level at pin 1 (LD) when the PLL is locked.
74HCT7046A Key Features
- Low power consumption
- Centre frequency up to 17 MHz (typ.) at VCC = 4.5 V
- Choice of two phase parators: EXCLUSIVE-OR; edge-triggered JK flip-flop
- Excellent VCO frequency linearity
- VCO-inhibit control for ON/OFF keying and for low standby power consumption
- Minimal frequency drift
- Operation 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
