INTEGRATED CIRCUITS DATA SHEET SAA7283 Terrestrial Digital Sound Decoder (TDSD3) Preliminary specification File under Integrated Circuits, IC02 1996 Oct 24 Philips Semiconductors Preliminary specification Terrestrial Digital Sound Decoder (TDSD3) Features - Single-chip solution including FM and vision filters, analog demodulator and audio switching - Dual standard with automatic selection between PAL system I and BGH including French NICAM L system) - Single low-radiation crystal oscillator for improved EMC - Stereo bitstream audio DACs - Programmable attenuator for matching levels of NICAM and FM audio sources at the output of the device - Full EBU NICAM 728 specification demodulation and decoding - Digital Audio Interface conforming with EBU/IEC 958 - Automatic mute function which switches from NICAM to FM sound when NICAM fails - patible with either single-ended or differential DQPSK input signals - Microputer controlled via I2C-bus (up to 400 k Hz specification). APPLICATIONS - Television receivers - Video cassette recorders. GENERAL DESCRIPTION The SAA7283 is a NICAM receiver solution, developing the well established high quality Terrestrial Digital Sound decoder family from Philips Semiconductors. This innovative IC with analog front-end, offers more impressive Features and flexibility with minimum external circuitry. ORDERING INFORMATION TYPE NUMBER SAA7283ZP SAA7283GP PACKAGE NAME SDIP52 QFP64 DESCRIPTION plastic shrink dual in-line package; 52 leads (600 mil) plastic quad flat package; 64 leads (lead length 1.95 mm); body 14 × 20 × 2.8 mm The SAA7283 takes, as input, a second IF (intercarrier) Terrestrial TV PAL signal, and performs all the Differential Quadrature Phase Shift Keying (DQPSK) demodulation, digital decoding and digital-to-analog conversion necessary to produce a plete NICAM receiver on a single integrated circuit. The demodulator function includes integrated baseband filters for pulse shaping and unwanted signal...
