has developed Silicon IP (180nm Logic CMOS) for TMDS and LVDS-compatible
CBDS Transceivers and support IP such as a wideband, low-jitter, integer PLL
and wideband, high-PSRR linear voltage regulators. These silicon IP Cores
implement patented or patent-pending technologies. Additionally, ComLSI has
researched and developed power management technologies and IP as described below.
Energy-Efficient Rapid Power MOSFET Switching
ComLSI's Power Management intellectual property includes patented
technology. Capable of SIMULTANEOUS gate-swing and ON-Resistance reduction, this power transistor bias and drive
technique reduces switching AND conduction losses in DC-to-DC converters and related applications. It is believed to be the only circuit
solution applicable to significantly reducing power transistor losses in switched converters. click on 'RPTS' above for a presentation on its benefits.
'True-Differential' Class-B Differential Signaling (CBDS) Driver
ComLSI's high-speed differential signaling technologies include patented
Drivers. Capable of either high voltage swings through high current output, or low power through
the use of the entire supply current drawn into signal development, this driver is LVDS compatible. Click on 'CBDS' above for more.
ComLSI's Active Packaging IP includes patented
or Stacked Active Passive Integration. SAPI is a technology direction combining active circuits, passive elements
and packaging. The trend towards smaller, higher performance devices with greater
functionality compels integration techniques such as package-on-package or PoP. SAPI
takes PoP and System-in-Package techniques a big step further by providing symbiotic
functionality within the package that amplifies the utility and performance of a component
or system while minimizing substrate real-estate use and cost.
Source-Coupled Differential Signaling (SCDL) Driver/Receiver
ComLSI's high-speed differential signaling technologies include patent-pending
fully-differential SCDL for HDMI over 25m cable
Drivers & Receivers. The drivers minimize transition energy consumption, undershoots and overshoots while increasing speed through source-coupled drive
and provide high-voltage compatibility in receivers. The drivers and receivers are DVI/HDMI compatible, and
are additionally suitable for driver and receiver equalization for enhanced multimedia cable range.
SerDes Circuits IP
ComLSI's products in the Serializer-Deserializer
area include wide-dynamic range, low-jitter clock extraction and synthesis PLL's,
high-speed, high-gain differential receivers, active and passive equalization,
and clock and data recovery loops: Pelican IP (180 nm)
