Chips&Media, Inc., the leading provider of Video Intellectual property (IP) cores will participate in SoCIP Symposium under the theme “The Era of Designing with System-prototyping IP” to be held over two days in Shanghai on June 1st and Beijing on June 3rd. This is the 3rd annual premier IP seminar and exhibition where major global SoC IP and design technology companies meet the Chinese SoC design professionals. At this event, Chips&Media will offer the opportunity to learn how to select the right video IP for high-performance SoC designs through delivering presentations, technical papers and product demonstrations.  

In the Chips&Media booth, attendees can see demonstrations of Chips&Media’s the latest video decoder IP core, Boda7503v2. It features full HD 1080p video decoding at 30fps with multi-standards support including H.264, MPEG-1/2/4, VC-1, DivX, H.263, RealVideo, Sorenson spark and even AVS. Also, the Boda7503v2 utilizes tiled memory addressing scheme and its proprietary bus protocol for enhanced memory management so that latency reduction, better memory efficiency and performance can be achieved. 

In addition to this, Chips&Media will introduce their 3rd generation video IPs, BODA950 which can decode full HD 1080p multi-format stream including Theora at 60fps and CODA960 which can encode full HD video stream with H.264 Baseline profile at 30fps. The papers will be available from the booth.  

About SoCIP 

SoCIP aims to serve the SoC design community by providing technologies and product information that enable precise SoC-building on the first try. Our vision is for a designer to rapidly assemble a SoC prototype by using commercial IP with minimal up-front cost, validate that the function is correct and then find the right service provider to turn the prototype into a real silicon – all this is done to ensure that your SoC investment will give strong returns. SoCIP is organized by S2C Inc. www.s2cinc.com and sponsored by leading silicon IP and SoC design technologies companies around the world.  For more information about SoCIP 2010 or to register, please visit www.socip.org.

MILPITAS, CA – May 24, 2010 – Linear Technology Corporation introduces the LTC3856, a two-phase single output high efficiency (up to 95%) synchronous step-down DC/DC controller with PolyPhase® operation, differential output voltage sensing and integrated phased-lock loop (PLL) synchronization. Up to 12 phases can be paralleled and clocked out of phase to minimize input and output filtering requirements for high current applications (up to 300A). The differential amplifier provides remote output voltage sensing of both the positive and negative terminals, enabling high accuracy regulation independent of IR losses in trace runs, vias and interconnects. Applications include high current ASIC and FPGA supplies, power distribution buses, high power audio amplifiers and network servers.

The LTC3856 operates with all N-channel MOSFETs from input voltages ranging from 4.5V to 38V and it can produce ±0.75% accurate output voltages from 0.6V to 5V. The output current is sensed by monitoring the voltage drop across the output inductor (DCR) or by using a sense resistor. Programmable DCR temperature compensation maintains an accurate and constant current limit set point over a broad temperature range. The powerful onboard gate drivers minimize MOSFET switching losses and enable the use of multiple MOSFETs connected in parallel. A fixed operating frequency can be programmed from 250kHz to 770kHz or can be synchronized to an external clock with its internal PLL. The device’s minimum on-time of just 90ns makes the LTC3856 ideal for high step-down ratio applications.

The LTC3856 incorporates an adjustable Stage Shedding™ technique to increase efficiency at light loads by eliminating gate charge and switching losses of one of its output stages. In addition, the LTC3856 can be configured for adjustable Burst Mode® operation to produce even higher efficiency at light loads. Its adaptive voltage positioning (AVP) minimizes the maximum transient voltage deviation during a load current step.

Tracking and sequencing functions allow the optimization of power-up and power-down of multiple power supplies. Additional features include current mode control, an onboard LDO for IC power, programmable soft start, a power good output and external VCC control.

The LTC3856 is available in thermally enhanced 38-lead SSOP or 32-lead 5mm x 5mm QFN packages and operates over a -40ºC to 125ºC operating junction temperature range. 1000-piece price starts at $3.12 each. Both versions are available from stock. For more information, visit http://www.linear.com/pr/3856.
