NXP Semiconductors TDA6403
The TDA6402A and TDA6403A differ from the TDA6402 and TDA6403 by the UHF port protocol in the I2C-bus mode (see Tables 3 and 4). The devices include two double balanced mixers and two oscillators for the VHF and UHF band respectively, an IF amplifier and a PLL synthesizer. The VHF band can be split-up into two sub-bands using a proper oscillator application and a switchable inductor.| Part No. | TDA6403 |
