I 2 C Bus Control Lineup
LA76810 Series
I 2 C Bus Control Lineup
LA76810 Series
The LA76810 series are I 2 C bus controller ICs that support the different TV broadcast formats used worldwide and aim for
rationalization of color TV set design, improved manufacturability, and lower total costs
Single crystal multiformat system that supports the different TV broadcast formats used worldwide
ICs optimal for each individual broadcast standard deployed as a pin-to-pin compatible lineup
· Multiformat system: LA76818A (YCbCr support), LA76828N (YCbCr and E/W support)
· NTSC system: LA76843N/LA76835A (YCbCr and E/W support), LA76835NM (YCbCr and E/W support)
Adjustment-free VIF/SIF, audio trap/audio bandpass filters
Adjustment- free horizontal resonator system
Simplified SG
Supply voltage: VCC = 5 V/9 V
Package: DIP54S (600mil), QIP80E (14 20) (LA76835NM only)
VIF/SIF
· Adjustment-free VCO, 4-mode audio trap/audio bandpass filter, buzz canceller
· RF AGC/video level
· SIF system automatic discrimination (The LA7973 is used as the automatic discrimination IC.)
Single crystal color system: PAL, NTSC, SECAM (The LA7642N is used as the SECAM decoder.)
Black stretch, sharpness control with coring on/off control, built-in variable Y system filters (Y-DL and chrominance trap)
Chrominance bandpass filter, demodulation ratio and angle control
