Description

The TDA9381PS is a highly integrated TV signal processor IC from the TDA93xx family (Philips/NXP), combining analog video processing, audio processing, and an embedded microcontroller into a single chip. It is specifically designed for CRT television receivers, particularly in cost-sensitive (economy) designs.

The various versions of theTDA935X/6X/8X PS/N2 series combine the functions of a TV signal processor together with aµ-Controller and US Closed Caption decoder. Most versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text. The ICs are intended to be used in economy television receivers with 90°and 110°picture tubes. The ICs have supply voltages of 8 V and 3.3 V and they are mounted in S-DIP envelope with 64 pins.

Key Architecture

  • TV signal processor + embedded µ-controller
  • Integrated video IF, chroma, and luminance processing
  • On-chip audio processing
  • Built-in Teletext and Closed Caption decoder
  • Internal RAM for Teletext pages

Design Insights (Important)

  • Separate analog and digital supply decoupling is critical
  • Crystal/clock stability affects video timing and MCU operation
  • Proper grounding reduces noise in video output
  • Teletext RAM size determines feature capability (1 vs 10 pages)
  • Firmware inside MCU is mask-programmed → limited customization

Advantages

  • Very high integration → minimal external components
  • Cost-effective for mass production
  • Built-in Teletext and caption features
  • Simplified system design

Typical Applications

  • CRT televisions (economy class)
  • Analog TV receivers
  • Low-cost display systems

APL5607 PDF Datasheet – 600mA Linear Regulator

Posted on by pinout

Part Number: APL5607

Function: 600mA, Linear Regulator for DC Fan Speed Control

Package: SOP-8 and TDFN3x3-8  Type

Manufacturer: ANPEC

Images:APL5607 PDF

Description

The APL5607 is a low quiescent current and low dropout linear regulator which is designed to power a DC fan and deliver up to 600mA output current. The output voltage follows the 1.6 times of VSET voltage and typical dropout voltage is only 220mV (typical) at 600mA output current.

The APL5607, APL5607A with low 140µA quiescent current is ideal for battery-powered system appliances and stable with a 2.2µF ceramic output capacitor. The features of current-limit (with foldback current) and overtemperature protection protect the device against current over-loads and over temperature.
