MXL301RF SILICON IC TUNER
GENERAL DESCRIPTION
MxL301RF is a highly integrated low‐power
silicon tuner IC targeting at all global analog
(NTSC, PAL, SECAM) and digital cable
standards (ITU‐T J.83 Annexes A and C [DVB‐
C] and Annex B [US Cable], DOCSIS, and
EURODOCSIS) as well as digital terrestrial
reception standards (DVB‐T/H, ATSC, ISDB‐T
13‐Segment, and DTMB). Broadband input
filtering and channel filtering have been
completely integrated on‐chip. This integration
enables a very compact design requiring a small
footprint, low bill‐of‐materials cost, and low
power consumption.
A signal at the 75 RF input is filtered and
converted to a programmable IF output of up to
44MHz. Automatic gain control, LO generation,
and channel selectivity functions are completely
integrated on the chip, which simplifies board‐
level design. All functions of the IC can be
controlled via I2C interface.
MxL301RF is available in a 5 x 5 mm2 32‐pin
QFN package.
Applications
• Hybrid applications involving both digital
and analog receivers for TVs
• Digital cable applications such as STBs,
cable modems, EMTAs, and cable DTAs
Features
• Tuning range from 44MHz to 1002MHz
• Integrated channel filtering requiring no
external SAW filters for digital applications
• On‐chip 90 dB gain
• On‐chip 107‐dB gain control range with
single AGC
On‐chip broadband power detector
• Low power consumption
170 mA typical (UHF)
• Programmable IF
Able to meet all common demodulator
interface requirements
• Programmable channel bandwidths of 6, 7,
and 8MHz
• Programmable IF spectrum inversion
• Reference clock output available for re‐use
by demodulators and additional tuners in
multi‐channel applications
• On‐chip voltage regulators enable single
supply 3.0V‐3.6V operation
It can also use an additional 1.7V‐2.0V
supply for lower power option
• Integrated on‐chip programmable loading
capacitors for the reference crystal
• I2C‐compatible digital control interface
