CD74HCT4046AE (TEXAS INSTRUMENTS)
Схема ФАПЧ, 38МГц, 4.5В до 5.5В, DIP-16
The CD74HCT4046AE is a high-speed CMOS logic Phase-locked Loop with VCO. High-speed silicon-gate CMOS device that is pin compatible with the CD4046B of the "4000B" series. They are specified in compliance with JEDEC standard number 7. The HCT4046A is phase-locked-loop circuits that contain a linear voltage-controlled oscillator (VCO) and three different phase comparators (PC1, PC2 and PC3). A signal input and a comparator input are common to each comparator. The signal input 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 4046A forms a second-order loop PLL. The excellent VCO linearity is achieved by the use of linear op-amp techniques.
- Excellent VCO frequency linearity
- VCO-inhibit control for ON/OFF keying and for low standby power consumption
- Minimal frequency drift
- Balanced Propagation Delay and Transition Times
- Significant Power Reduction Compared to LSTTL Logic ICs
- 10 LSTTL Loads (standard outputs) and 15 LSTTL loads (bus driver outputs) fanout
- VIL= 0.8V (maximum), VIH = 2V (minimum) Direct LSTTL input logic compatibility
