74HC7046AD,112 (NEXPERIA)
PLL, FREQ SYNTHESIZER, 19MHZ, SOIC-16
The 74HC7046AD,112 is a high-speed Si-gate CMOS Device specified in compliance with JEDEC standard no. 7. The 74HC/HCT7046 is phase-locked-loop circuit that comprises a linear voltage-controlled oscillator (VCO) and two different phase comparators (PC1 and PC2) with a common signal input amplifier and a common comparator input. A lock detector is provided and this gives a HIGH level at pin 1 (LD) when the PLL is locked. The lock detector capacitor must be connected between pin 15 (CLD) and pin 8 (GND). The input signal can be directly coupled to large voltage signals or indirectly coupled (with a series capacitor) to small voltage signals. A self-bias input/circuit keeps small voltage signals within the linear region of the input amplifiers. With a passive low-pass filter, the "7046" forms a second-order loop PLL. The excellent VCO linearity is achieved by the use of linear op-amp techniques.
- Low power consumption
- Excellent VCO frequency linearity
- VCO-inhibit control for ON/OFF keying and for low standby power consumption
- Minimal frequency drift
- Zero voltage offset due to op-amp buffering
