BA7078AS - Synchronization signal processor for high definition displays

Description

Pin No.

Functions Used to select whether to output the VDRV section of the HDRV output signal.

High : VDRV section of HDRV is output Low : VDRV section of HDRV is not output Input either the composite synchronization signal or the horizontal synchronization signal.

Features

  • 1) Operates on a single 5V power supply, with low power consumption. 2) Synchronization signal existence and polarity detec-tion output. 3) Adjustable clamp pulse width, allowing for the selec-tion of front or back editing. 4) Vertical synchronization separation is based on hori-zontal frequency tracking, for separation starting at 1H. 5) Minimal attached components. !Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Operating temperature Symbol VCC ∗1 Limit.

BA7078AF/AS Multimedia ICs Synchronization signal processor for high definition displays BA7078AF/AS The BA7078AF is a synchronization signal processing LSI chip designed for multiscan high-definition displays. It generates a synchronization signal and clamp pulse for three types of input signals: separate synchronization, composite synchronization, and synchronization on video. !Application CRT displays !Features 1) Operates on a single 5V power supply, with low power consumption. 2) Synchronization signal existence and polarity detec-tion output. 3) Adjustable clamp pulse width, allowing for the selec-tion of front or back editing. 4) Vertical synchronization separation is based on hori-zontal frequency tracking, for separation starting at 1H. 5) Minimal attached components.
