NXP Semiconductors TDA5631
The TDA5630 and TDA5631 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 9 V and are available in a very small package. The devices give the designer the capability to design an economical and physically small 3-band tuner.| Part No. | TDA5631 |
