74HCT9046A General Description


The 74HCT9046A is a high-speed Si-gate CMOS device. It is specified in compliance with "JEDEC standard no. 7A".

74HCT9046A 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
` 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
` ICC category: MSI.

74HCT9046A Typical Application

· 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
· Tone decoding
· Data synchronization and conditioning
· Voltage-to-frequency conversion
· Motor-speed control.
