74HCT9046A
PLL with band gap controlled VCO
The 74HCT9046A. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features and benefits
Operation power supply voltage range from 4.5 V to 5.5 V
Low power consumption
Complies with JEDEC standard no. 7A
Inhibit control for ON/OFF keying and for low standby power consumption
Center frequency up to 17 MHz (typical) at VCC = 5.5 V
Choice of two phase comparators:
PC1: EXCLUSIVE-OR
PC2: Edge-triggered JK flip-flop
No dead zone of PC2
Charge pump output on PC2, whose current is set by an external resistor Rbias
Center frequency tolerance ±10 %
Excellent Voltage Controlled Oscillator (VCO) linearity
Low frequency drift with supply voltage and temperature variations
On-chip band gap reference
Glitch free operation of VCO, even at very low frequencies
Zero voltage offset due to operational amplifier buffering
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Applications
FM modulation and demodulation where a small center 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
