FI1216MF Datasheet | NXP Semiconductors

FEATURES - Systems CCIR L/L’ and B/G - True 5 V device (low power dissipation) - Full frequency range from channel 2 (48.25 MHz) to channel 69 (855.25 MHz) - PLL controlled tuning .. - True-synchronous vision IF demodulator (PLL) FI1216MF MK2 - Demodulated video output, AF sound output, second sound IF output - I2C-bus control of tuning, address selection, AFC status information - plies with European regulations on radiation, signal handling and immunity (“CENELEC 55020, 55013”) - Small horizontally mounted metal housing. DESCRIPTION The FI1200MK2 family of front ends are designed to meet a wide range of RF applications in the PC Multi-Media environment. The FI1216MF MK2 type are available with a single 75 Ω input for TV reception. The input connector is available in either standard phono (female socket) or IEC (female socket). The tuning and bandswitching are performed through the built-in digitally controlled I2C-bus. All front ends meet the input immunity and radiation requirements of CENELEC. ORDERING INFORMATION TYPE FI1216MF MK2/HM/PH FI1216MF MK2/HM/IEC MARKING The following items of information are printed on a sticker that is on the top cover of the tuner: - Type number - Code number - Origin letter of factory - Change code - Year and week code. The FI1216MF MK2 consists of a tuner section and an IF section, which are all designed on a single PCB. The front-end is assembled in a metal housing made of a rectangular tin plated steel frame with front and rear covers which have soldered contacts to the frame. A single phono or IEC aerial socket is mounted on one side of the frame. All other connections are made via pins at the bottom. The tuner section is equipped with 3 tuned RF MOSFET input stages, with a 3-band mixer-oscillator IC, containing the oscillators, mixers and IF amplifier. Tuning and band switching in the tuner section are done with a digital programmable PLL tuning system. This enables tuning with step-size programmable between 31.25, 50.0 or...
