LM1882 Product details

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.

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.
