VERTICAL OUTPUT STAGE

TDA9379FA

The IC TDA9379FA is the vertical deflection booster circuit. Two supply voltages, +12V and 12V are needed to scan the

inputs VERT+ and VERT-, respectively. And a third supply voltage, +45V for the flyback limiting are needed. The vertical

deflection coil is connected in series between the output and feedback to the input.

TVTEXT CONTROLLER

(SDA5550M)

The SDA5550M is a single chip teletext decoder for decoding World System Teletext data as well as Video Program-

ming System (VPS), Program Delivery Control (PDC), and Wide Screen Signalling (WSS) data used for PAL plus

transmissions (Line 23). The device provides an integrated general-purpose, fully 8051-compatible Microcontroller with

television specific hardware features. Microcontroller has been enhanced to provide powerful features such as memory

banking, data pointers, and additional interrupts etc. The on-chip display unit for displaying Level 1.5 teletext data can

also be used for customer defined on screen displays. Internal XRAM consists of up to17 Kbytes. AK41 has the version

without internal ROM. This device can support external memory up to 1Mbyte ROM and RAM.TVTEXT Controller con-

tains a data slicer for VPS, WSS, PDC and TXT, an acceleration acquisition hardware module, a display generator for

Level 1.5 TXT and powerful On screen Display capabilities based on parallel attributes, and pixel oriented characters

(DRCS). The 8 bit Microcontroller operates at 360nsec cycle time (min). Controller with dedicated hardware does most of

the internal TXT acquisition processing, transfer data to/from external memory interface and receives/transmits data via

I2 C-firmware user interface. SDA5550M is realized in 0.25 micron technology with 2.5V supply voltage and 3.3V I/O

compatible.

The IC produces the following input or output control signals; AGC_CON, MODE_SW, L / L, PIP_MODS, PIP_SEL,

ON/OFF (stand-by), SC1..3_IN_AV (pin 8 information from 3 SCARTs), AFC, MUTE (to mute audio output IC), I2CEN.
