AN2493FH
Luminance and chrominance signal processing (PAL) IC for 8 mm VCR
Unit: mm
s Overview
The AN2493FH is a single chip LSI designed for a Y/ C main signal processing of PAL system normal 8 mm video. System cost can be cut down drastically by builtin of external filters and fc automatic adjustment.

Note) 1. Optimize C1, C2, C3, L1 and L2 to meet Xtal characteristics. 2. Adjustment should be done in the order of variable resistor (VR), V33 voltage and variable resistor so as to minimize the chroma signal at ADD out (pin 32) output. (At REC mode, line mode, chroma 100% input) 3. The application circuit diagram in this data is just a typical circuit example as a reference data for use, and whatever the loss caused or whatever the infringement of the third party's industrial property right by the use of this circuit is not our responsibility.
