Fairchild Semiconductor 74ACT715-R
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. The devices are capable of generating signals for both interlaced and noninterlaced modes of operation.GENERAL DESCRIPTION
All pulse widths are completely definable by the user. 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. These signals can be used to generate horizontal or vertical gating pulses, cursor position or vertical Interrupt signal. These devices make no assumptions concerning the system architecture. Line rate and field/frame rate are all a function of the values programmed into the data register
