The recommended power-up sequence is to first apply the analog power supply (VAA) and then the digital power supply (VDD). This ensures that the analog circuitry is powered up before the digital circuitry.
The SAA7114H/V2 can be configured for different video standards (e.g. PAL, NTSC, SECAM) by setting the appropriate values for the VID_STD[2:0] pins. The specific values for each standard can be found in the datasheet.
The maximum clock frequency for the SAA7114H/V2 is 27 MHz. Exceeding this frequency may result in unstable operation or damage to the device.
The clock signal for the SAA7114H/V2 should be a stable, low-jitter clock signal. It is recommended to use a crystal oscillator or a high-quality clock generator to ensure reliable operation.
The AGC pin is used to control the gain of the video amplifier. It can be connected to an external resistor or capacitor to adjust the gain, or it can be left unconnected for automatic gain control.
