NXP Semiconductors TDA5633
The TDA5632 and TDA5633 are monolithic integrated circuits 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. These low-power mixers/oscillators require a power supply of 9 V and are available in a very small package.| Part No. | TDA5633 |
