Overview
Functions and Features
Overview
Functions and Features
The LA76810 series are I2C 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, buzz canceller
· RF AGC/video level/FM level control
Black stretch, sharpness control with coring on/off control, built-in variable Y system filters (Y-DL and chrominance trap)
Chrominance bandpass filter, demodulation angle control
E/W support
