MC44C801 Datasheet - Motorola

MC44C801 (MC44C800 / MC44C801) Single Chip CMOS Broadband Tuner

The simplified block diagrams below shows the major sections of the IC. Input frequency range is 50 to 861 MHz. On the MC44C801, the gain of the internal LNA is set via the SPI bus depending on the input signal level. The MC44C800 utilizes an ext ernal variable gain device. The signal is then up con.

MC44C800/801 MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Brief Single Chip CMOS Broadband Tuner The MC44C800/801 Silicon Tuner ICs are highly integrated single chip broadband tuners for cable data and set-top applications. They receive 50 MHz to 861 MHz cable signals and convert them to a second IF of 36 MHz to 46 MHz. Typical applications include Cable Data Modems, Cable Digital and Analog Settop boxes, VoIP Telephony boxes, etc. These tuners meet all DOCSIS requirements for 64 and 256 QAM. T.
