MN83876A
Liquid Crystal Display Panel Source Driver
Overview
The MN83876A converts digital display data from a personal computer or engineering workstation into analog signal voltages for driving thin-film
transistor color LCD panels.
Features
Driver capable of displaying 260,000 colors with built-in D/A converter accepting 6-bit digital inputs Choice of 300 or 309 drive outputs Seven-segment gamma correction Data settings of 01 and 3E in addition to 00, 07, 17, 27, 37, and 3F for output voltage inflection points Drive system that does not require precharging Supports serial cascade connections. Automatic clock suspension after reading in specified data volume Choice of shift register shift directions Support for data inversion control at the clock cycle level. Digital portions operate at low voltages (2.5 to 3.6 V) Maximum operating frequency of 55 MHz (2.5 to 3.6 V) Choice of 3.3 or 5 V for analog portions
Applications
Personal computers and workstations (available for SVGA and XGA)
