SAA7197 Clock Generator Circuit for desktop video systems CGC

SAA7197 Description

INTEGRATED CIRCUITS DATA SHEET SAA7197 Clock Generator Circuit for desktop video systems (CGC) Product specification File under Integrated Circuits, .
SAA7197 The SAA7197 generates all clock signals required for a digital TV system suitable for the SAA719x family.

SAA7197 Features

* Suitable for Desktop Video systems
* Two different sync sources selectable
* PLL frequency multiplier to generate 4 times of input frequency
* Dividers to generate clocks LLCA, LLCB, LLC2A and LLC2B (2nd and 4th multiples of input frequency)
* PLL mode or VC

SAA7197 Applications

* in conjunction with memory controllers. The input signal LFCO is a digital-to-analog converted signal provided by the DMDS-SQPs horizontal PLL. It is the multiple of the line frequency: 7.38 MHz = 472 × fH in 50 Hz systems 6.14 MHz = 360 × fH in 60 Hz systems LFCO2 (TTL-compatible signal from an ext
