74ACT715 - Programmable Video Sync Generator

General Description

The ACT715 and ACT715-R are 20-pin TTL-input compatible devices capable of generating Horizontal, Vertical and Composite Sync and Blank signals for televisions and monitors.

All pulse widths are completely definable by the user.

Key Features

  • s Maximum Input Clock Frequency > 130 MHz s Interlaced and non-interlaced formats available s Separate or composite horizontal and vertical Sync and Blank signals available s Complete control of pulse width via register programming s All inputs are TTL compatible s 8 mA drive on all outputs s Default RS170/NTSC values mask programmed into registers s ACT715-R is mask programmed to default to a Clock Enable state for easier start-up into 14.31818 MHz RS170 timing Ordering Code: Order Number 74AC.

All pulse widths are completely definable by the user. The devices are capable of generating signals for both interlaced and noninterlaced modes of operation. Equalization and serration pulses can be introduced into the Composite Sync signal when needed. Four additional signals can also be made available when Composite Sync or Blank are used.
