Product specification
Clock signal generator circuit for digital
TV systems (SCGC)
SAA7157
FEATURES
Clock generation suitable for digital TV systems (line-locked)
PLL frequency multiplier to generate 4 times of input frequency
Dividers to generate clocks LL1.5A, LL1.5B, LL3A and LL3B (4th and 2nd multiples of input frequency)
PLL mode or VCO mode selectable
Reset control and power fail detection
Suitable for applications with feature box and picture memory
GENERAL DESCRIPTION
The SAA7157 generates all clock signals required for a digital TV system suitable for the SAA715x family and the
SAA7199B (DENC). The circuit operates in either the phase-locked loop mode (PLL) or voltage controlled oscillator
mode (VCO).
