74ACT71574ACT715-R Programmable Video Sync Generator www.DataSheet4U.com November 1988 Revised December 1998 74ACT71574ACT715-R 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. 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. 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...
