NTE NTE15039 Datasheet

NTE15039

Integrated Circuit

VHS/VCR Chroma Signal Proessor for

NTSC/PAL/SECAM Systems

Description:

The NTE15039 is a multifunctional IC in a 24–Lead DIP type package that contains VHS VCT chroma
signal processing circuitry. Since the package is small and a minimum number of external compo­nents are required, the NTE15039 occupies much less space on the PC board thus facilitating VCR
design. The chroma section is made adjustment–free (except REC chroma level) thus streamlining
the manufacture of VCRs

Features:

D Designed for NTSC/PAL/MESECAM Systems
D Adjustment–Free Chroma Section (Except REC Chroma Level)
D Few External Components Required
D LPF Usable for REC/PB
D Multifunctional:

2fSC Generator for CCD Drive
Function to Select APC Loop Input Signal Passed/Not Passed Through Comb Filter
3rd Lock Protector of VXO
