APPLICATIONS
GENERAL DESCRIPTION
The TDA5736 and TDA5737 are monolithic integrated circuits that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuners. These low power mixer/oscillators require a power supply of 5 V and are available in a very small package.
These devices give the designer the capability to design an economical and physically small 3-band tuner.
They are suitable for European standards, as illustrated in Fig.17, with the following RF bands: 48.25 to 168.25 MHz,
175.25 to 447.25 MHz and 455.25 to 855.25 MHz. With an appropriate tuned circuit, they are also suitable for NTSC all channel tuners (USA and Japan).
The tuner development time can be drastically reduced by using these devices.
TDA5736; TDA5737
