Product Summary
The TDA5632M/C1 is a monolithic integrated circuit that perform VHF and UHF mixer/oscillator functions in TV and VCR cable tuners. With correct oscillator application and by using a switchable inductor to split the VHF band into two sub-bands, the full VHF/UHF TV bands can be covered. The TDA5632M/C1 requires a power supply of 9 V and are available in a very small package. Applications are (1)Cable tuners for TV and VTR; switched concept for VHF; (2)Recommended RF bands for Europe: 48.25 to 105.25 MHz, 112.25 to 294.25 MHz and 471.25 to 855.25 MHz; (3)Recommended RF bands for the USA: 55.25 to 133.25 MHz, 139.25 to 361.25 MHz and 367.25 to 801.25 MHz.
Parametrics
TDA5632M/C1 absolute maximum ratings: (1)VP supply voltage: -0.3 to +10.5 V; (2)VSW switching voltage: 0 to 10.5 V; (3)IO output current of each pin referenced to ground: 10 mA; (4)tsc maximum short-circuit time (all pins): 10 s; (5)Tstg IC storage temperature: -55 to +150 °C; (6)Tamb operating ambient temperature: -20 to +85 °C; (7)Tj junction temperature: +150 °C.
Features
TDA5632M/C1 features: (1)Balanced mixer with a common emitter input for band A; (2)2-pin oscillator for band A; (3)Balanced mixer with a common base input for band C; (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 a 75 W load; (7)Band gap voltage stabilizer for oscillator stability; (8)Electronic band switch; (9)External IF filter connected between the mixer output and the IF amplifier input.
