D1379C integrated circuit application circuit

D1379C is an integrated circuit for black and white TV line and field scanning . Its main functions are: synchronous separation, AFC, line oscillation and line pre-excitation, frame oscillation and output, boost circuit, etc. Different from D1031 It integrates AFC, line oscillation, and line pre-excitation into the circuit, making the external components less. The application example is shown in the figure.

The application principle of D1379C is: the full TV signal from the pre-view output is input from the 15-pin to the synchronous sharer in the circuit, in the synchronous separator, the frame sync pulse

Do you know what is ENEPIG in PCB?
 What is ENEPIG?ENEPIG-Electroless Nickel Electroless Palladium Immersion Gold is a surface finish for Printed Circuit Boards.ENEPIG works well with lead free and conventional eutectic solder alloys.This is the best way for gold wire bonding. Advantages for ENEPIG:

1.[Black Nickel" free – no possibility of grain boundary corrosion of nickel surface by immersion gold
2.Palladium acts as an additional barrier layer to further reduce copper diffusion to surface, thus ensuring good solderability
3.Palladium completely dissolves into solder, without leaving an excessively high P% rich interface, exposing an oxide-free nickel surface allowing reliable formation of Ni/Sn intermetallic
5.Withstands multiple lead-free reflow soldering cycles
6.Demonstrates excellent gold wire bondability

7.Process costs substantially lower than electrolytic nickel gold or electroless nickel electroless gold
