General Description

The ’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 generating signals for both interlaced and noninterlaced modes of operation.

Key Features

n Maximum Input Clock Frequency > 130 MHz n Interlaced and non-interlaced formats available n Separate or composite horizontal and vertical Sync and Blank signals available n Complete control of pulse width via register programming n All inputs are TTL compatible n 8 mA drive on all outputs n Default RS170/NTSC values mask programmed into registers n 4 KV minimum ESD immunity n ’ACT715-R/LM1882-R is mask programmed to default to a Clock Enable state for easier start-up into 14.31818 MHz RS170 ti.
