Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
Intersil estimates that more than two-thirds of the projected VRM 9.0 worldwide market will include the Endura circuit.
VRM 9.0 is an Intel power management specification that addresses the power requirements for Pentium 4-class processors used in high-availability, high-volume data environments, such as workstation, Internet access, financial institution and reservation system servers and other advanced computer systems.
The specification ensures that power delivered to multiple processors is correctly regulated to maximise performance, save power and prevent data loss.
"VRM 9.0 is the highest performance power specification on the market", said Rick Furtney, vice president and general manager of Intersil's Endura Power Management products.
"Our power management solutions meet or exceed VRM 9.0 specifications and with market leaders Delta, Astec and Artesyn already choosing them for their new generation products, we are gaining the lion's share of the high performance power management market".
High-performance systems often require up to eight CPUs and demand highly regulated power levels including multiple VRMs to meet fluctuating power requirements.
When VRMs work independently, current imbalances can occur, resulting in increased component temperatures, decreased system reliability and increased downtime.
Intersil's Endura circuit solves the current imbalance problem by configuring multiple VRMs so that they equally share the total current demand of the processors resulting in higher reliability due to reduced peak thermal demands.
It also allows multiple VRMs to respond better to dynamic demands from individual microprocessors resulting in improved performance.
