The company announced a new DOCSIS 3.0 wideband tuner chip capable to handle a
wider (100 MHz) and faster (160 Mbps) cable
modem connection to homes, competing with
high-powered fiber-to-the-home networks.
Featuring:
The chip is capable to tune between 50 MHz-1
GHz. A cable plant of 750 MHz or 860 MHz would
be able to grow to 1 GHz, and would allow the
addition of about 20 6 MHz channels, which could
be used for IPTV services, HDTV, channel
bonding, etc.
According with Microtune the spec would permit
the bonding of non-adjacent 6 MHz channels
from a 64 MHz spectrum range, which the
Wideband tuner can raise to 100 MHz, handling
about 16 bonded channels.
Equivalent functionality of four DOCSIS 2.0 tuners,
RF footprint shrinking by 75%,
Power consumption cut by 75%,
Reduced BOM costs for DOCSIS 3.0 cable equipment manufacturers,
First 1-gigahertz (GHz) input DOCSIS® 3.0 compliant,
Integrated miniature package,
Radio frequency (RF) bill of materials costs reduction,
Optimized to work with radio frequencies in the 50-MHz to 1-GHz range of the cable
spectrum,
Supports DOCSIS 3.0 channel bonding technology (a bandwidth expansion technique
that combines four DOCSIS channels to significantly increase data rates),
Accepts bonded channels within bandwidths up to 100 MHz when paired with a
DOCSIS 3.0-capable demodulator, engineered to function in a much more hostile
signal environment than that experienced by conventional cable modem tuners,
Able to process wideband bonded channels in the presence of multiple interfering
signals, while meeting stringent DOCSIS 3.0 sensitivity and adjacent channel
interference requirements.
Sampling expected for 2Q07 to select customers,
