Programmable Video Sync General DescriptionThe ’ACT715/LM1882 and ’ACT715-R/LM1882-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 generat ing signals for both interlaced and noninterlaced modes of operation. Equalization and serration pulses can be intro duced 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 sys tem architecture. Line rate and field/frame rate are all a function of the values programmed into the data registers, the status register, and the input clock frequency The ’ACT715/LM1882 is mask programmed to default to a Clock Disable state. Bit 10 of the Status Register, Register 0, defaults to a logic ‘‘0’’. This facilitates (re)programming before operation.
