SAA7157 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).

| VDDD | digital supply voltage (pins 8 and 17) | -0.5 | 7.0 | V |
| Vdiff GND | difference voltage VDDA - VDDD | - | ±100 | mV |
| VO | output voltage (IOM = 20 mA) | -0.5 | VDDD | V |
| Ptot | total power dissipation (DIL20) | 0 | 1.1 | mV |
| Tstg | storage temperature | - 65 | 150 | °C |
| Tamb | operating ambient temperature | 0 | 70 | °C |
| VESD | electrostatic handling(1) for all pins | - | tbf | V |
1. Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is recommended to take normal handling precautions appropriate to "Handling MOS devices".
