BA7078AF Datasheet

BA7078AF Synchronization signal processor for high definition displays

Pin No. Pin name 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. Input is clamped, and i.

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 Limits 7.0 450(BA7078AF) 600(BA7078AS) −25 to +75 ∗2 Unit V mW °C °C Pd Topr −55 to +125 Tstg Storage .
