【文字介紹】The FQD1236 MK5 belongs to the new family of highly-featured hybrid frontends, which are designed to meet a wide range of RF applications in the PC/LCD/Plasma environment. The FQD1236 MK5 combines the functions of an ATSC/QAM amplifier for connection to an ATSC/QAM channel decoder.
The FQD1236 MK5 allows an active loopthrough function option (FQD1236L MK5).
Avoltage switch is built-in digital (I2C) PLL tuning system. A DC-DC converter circuit is built into the FQD1236 MK5 to synthesize the tuning voltage required, thus making the frontend a true 5V device.
For PIP/Double Window application, a Second module address can be set for both the tuner and IF part.
