TDA9370PS Microprocessor

Description

The TDA9370PS is microprocessor (CPU) for TV.

A microprocessor for TV is a type of microprocessor specifically designed to be used in televisions. It is a specialized integrated circuit that acts as the central processing unit (CPU) of the television.

The microprocessor is responsible for controlling various functions of the TV, such as the display, audio output, input selection, and other features. It receives commands from the remote control or the buttons on the TV, processes them, and then executes the necessary actions.

TDA8842 tv processor

Description

The various versions of the TDA8842 series are I2C-bus controlled single chip TV processors which are intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers. The N2 version is pin and application compatible with the N1 version, however,a new feature has been added which makes the N2 more attractive. The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required). The setting of the various frequencies (33.4, 33.9, 38, 38.9, 45,75 and 58.75 MHz) can be made via the I2C-bus.
