Description

The 74ACT715-RSC 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 of the 74ACT715-RSC 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.

The 74ACT715-RSC make no assumptions concerning the system 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 74ACT715-RSC 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.

The 74ACT715-RSC is the same as the ACT715 in all respects except that the ACT715-R is mask programmed to default to a Clock Enabled state. Bit 10 of the Status Register defaults to a logic "1". Although completely (re)programmable, the ACT715-R version is better suited for applications using the default 14.31818 MHz RS-170 register values. This feature allows power-up directly into operation, following a single CLEAR pulse.

The 74ACT715-RSC is a type of 20-pin TTL-input compatible devices, which is able to generate Horizontal, Vertical an d Composite Sync and Blank signals for televisions and monitors. All pulse widths are completely definable by the us er. The device can generate signals for both interlaced and noninterlaced modes of operation.
