MaxLinear Launches Highest Performance Single-Chip Receiver for ISDB-T Set-Top Boxes

Business Wire
MaxLinear Inc. (NYSE:MXL), a leading provider of integrated
radio frequency (RF) and mixed-signal integrated circuits for
broadband communications applications, today announced the MxL683,
its next-generation high-performance, single-chip receiver for
ISDB-T and SBTVD-T terrestrial set-top box applications.
The MxL683 is a monolithic system-on-chip based on 65nm CMOS
process technology. The device integrates MaxLinear’s latest “super
radio” core with a state-of-the-art ISDB-T demodulator to deliver
exceptional system performance, even in very difficult terrestrial
broadcast environments commonly found in Brazil and other Latin
American countries. The MxL683 includes an embedded CPU for
adaptive tuner and demodulator performance control, fast channel
acquisition, and advanced power management. It also integrates
voltage regulation, RF loop-through output and clock output for
sharing a single crystal with multiple devices.
The MxL683 device was designed to provide excellent rejection of
out-of-band interference from 4G/LTE, Wi-Fi, Satellite and MoCA
signals. This performance makes the MxL683 an ideal choice for
hybrid set-top boxes that combine multiple reception (e.g.,
satellite and terrestrial) and connectivity technologies in a
single box, or on a single cable.
“MaxLinear’s ISDB-T tuner technology was already well proven,
but we were surprised at the extremely good demodulator
performance, even in the most stringent time varying channel or
echo conditions,” said Prof. Dr. Gunnar Bedicks, Chief Researcher,
Mackenzie University Digital TV Laboratory, a leading digital TV
laboratory for transmission and reception systems in Sao Paulo,
Brazil. “The demodulator outperformed all other commercially
available solutions that we have tested, in the lab and in the
field.”
“The MxL683 is the industry’s first true single-chip receiver
for ISDB-T set-top boxes. The typical complexity and risks
associated with RF design is virtually eliminated with this
device,” said Brian Sprague, MaxLinear Vice President and General
Manager. “This solution allows our customers to get to market
faster with better performance, lower cost and lower risk, the
ultimate signs of a value-added product.”
Technical Highlights
Thanks to a noise figure lower than 4dB and exceptional
demodulator C/N performance, the MxL683 achieves best-in-class
sensitivity, which is important for low cost set-top boxes in
emerging countries with widely scattered transmitters and typical
weak signal conditions. The unmatched adjacent and co-channel
interferer immunity provides assurance that set-top boxes will be
reliable and robust in a crowded TV spectrum.
The MxL683 is fully compliant with the Japanese ISDB-T (ARIB
STD-B21) and Brazilian SBTVD-T (ABNT NBR 15604) terrestrial TV
receiver specifications. Additional features include auxiliary
channel decoding for emergency broadcast warning system, high
accuracy receiver signal strength indicator (RSSI), and fast
channel scan algorithm to reduce the set-top box scan time by up to
50 percent.
MxL683’s power consumption is approximately 470 milliwatts (mW)
in active mode and 25mA in standby mode. The low power consumption
and ultra-small 7 mm x 7 mm footprint make it an ideal solution for
low cost, small form-factor designs as well as multi-tuner set-top
boxes with personal video recorder (PVR) capabilities.
The MxL683 is currently sampling in a 7mm x7mm 48-QFN package. A
complete reference design kit with hardware, software and full
documentation is available for both single and dual-channel
applications.
