LMK04808 datasheet

 

Description

The LMK04800 family is the industry’s highest performance clock conditioner with superior clock jitter cleaning, generation, and distribution with advanced features to meet next generation system requirements. The dual loop PLLatinum™ architecture enables 111 fs rms jitter (12 kHz to 20 MHz) using a low noise VCXO module or sub-200 fs rms jitter (12 kHz to 20 MHz) using a low cost external crystal and varactor diode.

Features

1. Ultra-Low RMS Jitter Performance
(1) 111 fs RMS Jitter (12 kHz to 20 MHz)
(2) 123 fs RMS Jitter (100 Hz to 20 MHz)

2. Dual Loop PLLatinum™ PLL Architecture

3. Integrated Low-Noise Crystal Oscillator Circuit

4. Holdover Mode when Input Clocks are Lost

5. Automatic or Manual Triggering/Recovery

74AC191SCX Datasheet PDF – Up/Down Counter

Part Number: 74AC191SCX

Function: Up/Down Counter with Preset and Ripple Clock

Package: SOIC 16 Pin type

Manufacturer: Fairchild Semiconductor

Pinouts:

74AC191SCX datasheet

 

Description

The 74AC191SCX, 74AC191, 74191 is a reversible modulo 16 binary counter. It features synchronous counting and asynchronous presetting. The preset feature allows the AC191 to be used in programmable dividers. The Count Enable input, the Terminal Count output and the Ripple Clock output make possible a variety of methods of implementing multistage counters. In the counting modes, state changes are initiated by the rising edge of the clock.

Features

1. ICC reduced by 50%
2. High speed—133 MHz typical count frequency
3. Synchronous counting
4. Asynchronous parallel load
5. Cascadable
6. Outputs source/sink 24 mA
