IC WORKS Introduces Frequency-Timing Generators Supporting Intel's 440BX Chip Set for Pentium II and Pentium Pro Processors

Business Wire, Jan 20, 1998

SAN JOSE, Calif.--(BUSINESS WIRE)--Jan. 20, 1998--IC WORKS, Inc. today introduced the industry's broadest range of frequency-timing generators (FTGs, or clock ICs) supporting Intel's 440BX chip set for Pentium II and Pentium Pro processors.

The IC WORKS product offerings have the best jitter and EMI suppression performance of any FTG products supporting the 440BX chip set on the market.

Products are available in a range of configurations including desktop/server applications, mobile, and low cost, with and without spread spectrum EMI suppression. The W48C101 clock generator and W40S01 clock buffer are 48 pin SSOP devices fully compliant to Intel's specification and architecture with support for four DIMMs, dual processors, USB, super I/O, IOAPIC, and IIC interface.

According to IC WORKS' VP of marketing Barry Leff, the W48C101 has demonstrated industry leading jitter performance of as low as 130 picoseconds in third party testing.

For mobile applications, the W48S111 Clock Generator and W40S11 Buffer are available in 28 pin SSOP packages. They provide the ability to stop the CPU and PCI bus clocks. A low power-standby pin and support for two DIMMs is also included.

The W48S111 Clock Generator and W40S11 Buffer in 28 pin SOIC packages are targeted at applications where low cost is critical. They include support for USB, Super I/O, IOAPIC, and three DIMMs. The W40S12 can be substituted for the W40S11 in designs requiring support of four DIMMs.

Most of IC WORKS' frequency timing generators for the 440BX-chip set are available with or without IC WORKS' patent-pending implementation of spread spectrum EMI suppression technology.

Leff stated that "IC WORKS' EMI Suppression techniques allow us to achieve 2-3 dB additional EMI reduction when compared to other spread spectrum modulation methods, without impacting performance. That could be the last few dB needed for a customer to pass FCC tests."

According to Leff, samples and IBIS models for the 440BX-family of clock generators and buffers are available now.

IC WORKS is a leading manufacturer of frequency timing generators that are used in Personal Computer, Communications, Wireless, and General Purpose applications. The company was founded in 1992, is privately held, and is headquartered in San Jose.
