3 / 55 page 2004 Mar 22 3 Philips Semiconductors Product specification 5 V mixer/oscillator and low noise PLL synthesizer for hybrid terrestrial tuner (digital and analog) TDA6650TT; TDA6651TT 1 FEATURES • Single-chip 5 V mixer/oscillator and low phase noise PLL synthesizer for TV and VCR tuners, dedicated to hybrid (digital and analog) as well as pure digital applications (DVB-T) • Five possible step frequencies to cope with different digital terrestrial TV and analog TV standards • Eight charge pump currents between 40 and 600 µAto reach the optimum phase noise performance over the bands • Automatic Loop Bandwidth Control (ALBC) sets the optimum phase noise performance for DVB-T channels • I2C-bus protocol compatible with 2.5, 3.3 and 5 V microcontrollers: – Address + 5 data bytes transmission (I2C-bus write mode) – Address + 1 status byte (I2C-bus read mode) – Four independent I2C-bus addresses • Five PMOS open-drain ports with 15 mA source capability for band switching and general purpose; one of these ports is combined with a 5-step ADC • Wide band AGC detector for internal tuner AGC: – Six programmable take-over points – Two programmable time constants – AGC flag • In-lock flag • Crystal frequency output buffer • 33 V tuning voltage output • Fractional-N programmable divider • Balanced mixers with a common emitter input for the low band and for the mid band (each single input) • Balanced mixer with a common base input for the high band (balanced input) • 2-pin asymmetrical oscillator for the low band • 2-pin symmetrical oscillator for the mid band • 4-pin symmetrical oscillator for the high band • Switched concept IF amplifier with both asymmetrical and symmetrical outputs to drive low impedance or SAW filters i.e. 500 Ω//40 pF. 2 APPLICATIONS • Digital and analog terrestrial tuners (OFDM, PAL, etc.) • Cable tuners (QAM) • Digital TV sets • Digital set-top boxes. |
