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.
They utilize a double conversion architecture with an external first IF
SAW filter at 1120 MHz, and a second IF in the range of 36 MHz to 46
MHz. Both the MC44C800 and the MC44C801 are
identical, with the exception that the MC44C801 has a bus
programmable variable gain LNA with 21 dB of gain control.
The MC44C800 does not have the LNA.
A summary of the features is given below:
10/28/03 Rev 0.12
Integrated frequency synthesizers and prescalers.
One fully integrated VCO and one VCO requiring
only an external inductor.
Up conversion mixer.
Down conversion mixer.
Variable Gain LNA with 21 dB gain control
(MC44C801 only).
Reference oscillator circuit (using an external 25
MHz crystal).
Minimum CTB of – 66 dBc, CSO of –60 dBc and
XMod of –57 dB with +3 dBmV AGC attack point.
Typical noise figure of MC44C801 is 6.2 dB.
Phase noise @ 10 KHz offset of –94 dBc/Hz,
typical.
Single 5 V supply operation.
SPI bus interface.
Internal self-diagnostic circuits.
Power down mode with fast start-up.
No external Image Filter required.

... Freescale Semiconductor, Inc. 1 Functional Description The simplified block diagrams below shows the major sections of the IC. Input frequency range 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 converted to 1120 MHz and passed through the first IF filter ...
