Hardware Items 2.1. Filtering of Power Supply TVText Pro Design Guide 1. Introduction The purpose of this application note is to give a brief overview of the most important hardware aspects of the TVText Pro, e.g. slicer performance, oscillator, and hardware design. The TVText Pro requires two different power supply voltages. The 3.3-V supply is used to drive all port pins and address/data lines. The 2.5 V is used for the CPU core and the analog units of the TVText Pro. It is important for the hardware designer to take special note of the stability and noise on the 2.5-V domain. To avoid interference on the power supply lines and improve the analog performance (e.g. slicer, ADC) of the TVText Pro, it is recommended to divide the power supply into different sections, which are separated from each other by LC-filters. The number of power supply pins assigned to the different power supply sections depends on the package type of the TVText Pro. The tables below show pin assignments for the voltage domains in each of the four available package types.

Introduction The TVText Pro Evaluation Board is a versatile tool which provides quick access to the capabilities of TVText Pro's powerful architecture. To enable applications to be developed quickly and easily, the TVText Pro Evaluation Board is fitted with a variety of peripherals for connections to the outside world. This document applies to version 2 or higher of the TVText Pro Evaluation Board. Version 2 can clearly be seen on the board by the marking B004-V002. 1.1. Features of the TVText Pro Evaluation Board CPU: ­ TVText Pro in open top socket (MQFP100 package) Memory: ­ FLASH/EPROM memory up to 512 k x 8 (3.3 V, PLCC32 package) ­ SRAM 512 k x 8 (3.3 V, SO32 package) ­ NV-Memory (3.3 V, DIP8 package, I2C controlled) Universal Connector Reset Button NVM RS232 Connector Infrared Decoder SCART Connector (RGB Out) 4 Mbit SRAM Power LED Flash/Eprom +5 V Power Supply Input CVBS IN SyncSeparator 6 MHz Crystal +2.5 V Adjustment +3.3 V Adjustment Fig. 1­1: TVText Pro Evaluation Board Micronas Nov. 26, 2003; 6251-556-3-2AK 1 SDA 55xx 2. Getting Started 2.1. Jumper Settings An overview of all jumpers and switches of the TVText Pro Evaluation Board is shown in Table 2­1. The setting recommended in the last column "Setting" is used for running the demonstration software (P090Vxxx : 10 pages or P098Vxxx: 252 pages) with a television connected via the SCART connector. APPLICATION NOTE KITS/BOARDS 2.2. How to Start the Demonstration After setting the jumpers to the right position, proceed through the following instructions to start the demonstration software: ­ connect an antenna to a TV set and tune the TV (video picture on screen) ­ connect the TV set via a SCART cable to the TVText Pro Evaluation Board ­ connect a stable +5 V power supply unit (300 mA) to the power supply input ('POWER 5 V'
