Product Summary
The TDA5637BT/C1 is a monolithic integrated circuit that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuner. The low-power mixer/oscillator require a power supply of 9 V and are available in a very small package. The TDA5637BT/C1 gives the designer the capability to design an economical and physically small 3-band tuner. Applications are (1)3-band all channel TV and VCR tuners; (2)Any standard.
Parametrics
TDA5637BT/C1 absolute maximum ratings: (1)Supply voltage: -0.3 to +10.5 V; (2)Switching voltage: 0 to +10.5 V; (3)Output current of each pin to ground: -10 mA; (4)Maximum short-circuit time (all pins): 10 s; (5)IC storage temperature: -55 to +150 °C; (6)Operating ambient temperature: -10 to +80 °C; (7)Junction temperature: +150 °C.
Features
TDA5637BT/C1 features: (1)Balanced mixer with a common emitter input for band A (single input); (2)2-pin oscillator for bands A and B; (3)Balanced mixer with a common base input for bands B and C (balanced input); (4)4-pin oscillator for band C; (5)Local oscillator buffer output for external prescaler; (6)SAW filter preamplifier with a low output impedance to drive the SAW filter directly; (7)Band gap voltage stabilizer for oscillator stability; (8)Electronic band switch; (9)External IF filter between the mixer output and the IF amplifier input; (10)Pin-to-pin compatible with TDA5636; TDA5637 family (same function with asymmetrical IF output).
