Product data sheet
1. General description
TDA6500TT and TDA6501TT are programmable 2-mixer, 3-oscillator and synthesizer MOPLLs intended for pure 3-band tuner concepts. The device includes two double balanced mixers for the low and mid/high bands and three oscillators for the low, mid and high bands, respectively. Other functions are an IF amplifier, a wide-band AGC detector and a PLL synthesizer. Two pins are available between the mixer output and the IF amplifier input to enable IF filtering for improved signal handling. The device can be controlled according to the I2C-bus format.
2. Features
s Single-chip, 5 V mixer/oscillator and synthesizer for TV and VCR tuners s I2C-bus protocol compatible with 3.3 V and 5 V microcontrollers: x Address + 6 data bytes transmission x Address + 1 status byte (I2C-bus read mode) x Four independent I2C-bus addresses s Two PMOS open-drain ports with 5 mA source capability to switch high band and FM sound trap (P2 and P3) s One PMOS open-drain port P1 with 20 mA source capability to switch the mid band s One PMOS open-drain port P0 with 10 mA source capability to switch the low band s Five step, 3-bit Analog-to-Digital Converter (ADC) and NPN open-collector general purpose port P6 with 5 mA sinking capability s NPN open-collector general purpose port P4 with 5 mA sinking capability s Internal AGC flag s In-lock flag s 33 V tuning voltage output s 15-bit programmable divider s Programmable reference divider ratio: 64, 80 or 128 s Programmable charge pump current: 60 µA or 280 µA s Varicap drive disable s Balanced mixer with a common emitter input for the low band (single input) s Balanced mixer with a common base input for the mid and high bands (balanced input) s 2-pin asymmetrical oscillator for the low band s 2-pin asymmetrical oscillator for the mid band s 4-pin symmetrical oscillator for the high band
