FQD1116ME/IV
The FQD1116 belongs to the new family of highly-featured hybrid frontends, which are
designed to meet a wide range of RF applications. The FQD1116 combines the functions
of a DVB-T digital tuner and a multi-standard TV IF demodulation unit for both positive and
negative modulated TV systems. The unit includes a 7 MHz digital SAW filter with an IF
AGC amplifier for connection to the DVB-T channel decoder. The FQD1116 is intended
for CCIR L/L’ (France), B/G, I and D/K systems and DVB-T broadcast.
The frontends have a built-in digital (I2C) PLL tuning system. A DC-DC converter circuit is
built into the FQD1116 to synthesize the tuning voltage required, thus making the frontend
a true 5V device.
