Overview
INTEGRATED CIRCUITS DATA SHEET TDA9321H I2C-bus controlled TV input processor Preliminary specification File under Integrated Circuits, IC02 1998 Dec 16 Philips Semiconductors Preliminary specification I2C-bus controlled TV input processor FEATURES • Multistandard Vision IF (VIF) circuit with Phase-Locked Loop (PLL) demodulator • Sound IF (SIF) amplifier with separate input for single reference Quasi Split Sound (QSS) mode and separate Automatic Gain Control (AGC) circuit • AM demodulator without extra reference circuit • Switchable group delay correction circuit which can be used to compensate the group delay pre-correction of the B/G TV standard in multistandard TV receivers • Several (I2C-bus controlled) switch outputs which can be used to switch external circuits such as sound traps, etc.
• Flexible source selection circuit with 2 external CVBS inputs, 2 Luminance (Y) and Chrominance (C) (or additional CVBS) inputs and 2 independently switchable outputs • Comb filter interface with CVBS output and Y/C input • Integrated chrominance trap circuit • Integrated luminance delay line with adjustable delay time • Integrated chrominance band-pass filter with switchable centre frequency • Multistandard colour decoder with 4 separate pins for crystal connection and automatic search system • PALplus helper demodulator • Possible blanking of the helper signals for PALplus and EDTV-2 • Internal baseband delay line • Two linear RGB inputs with fast blanking; the RGB signals are converted to YUV signals before they are supplied to the outputs; one of the RGB inputs can also be used as YUV input ORDERING INFORMATION TYPE NUMBER TDA9321H PACKAGE NAME QFP64 DESCRIPTION plastic quad flat package; 64 leads (lead length 1.
95 mm); body 14 × 20 × 2.
8 mm TDA9321H • Horizontal synchronization circuit with switchable time constant for the PLL and Macrovision/subtitle gating • Horizontal synchronization pulse output or clamping pulse input/output • Vertical count-down circuit • Vertic...
