1) CM0021AF
As a digital convergence IC, this inputs HBLK and VBLK, adjusts a register in IC, makes
and supplies a digital convergence waveform of RH, GH, BH, RV, GV and BV. It also has
Save U-Com function and controls EEPROM (I503: 24WC32) which stores the
convergence control data by the order of Master U-Com.
The main features of this IC are as follows.
1-1) Feature
Multiscan : NTSC/PAL/HDTV, Progressive/Interlace
6ch/16bits Digital Outputs for Convergence Correction
2ch Analog Outputs for Dynamic Focus
Test Pattern Generator for Convergence
2-Port IIC Interface for EEPROM and U-COM
