CST Selects Inphi's INCU877 PLL Clock Driver for SP3000-DDR2 Testers

10/18/2004 - Inphi® Corporation, the performance leader in precision timing devices, announced that CST, Inc. selected its INCU877 PLL Clock Driver integrated circuit (IC) as the memory clock buffer for use on the CST SP3000-DDR2 testers. Citing engineering design excellence and high quality performance as key factors in its selection of Inphi's ICs, CST is currently utilizing the INCU877 PLL Clock Driver in its pilot production with plans for volume use as the testers ramp up to regular production.

"We are pleased with the technology that Inphi engineers have applied to reduce the phase jitter and enhance the duty cycle characteristic of the part," said Cecil Ho, President of CST. "These two parameters are absolutely crucial to our tester margin and performance, and ensure our customers will receive better performing, more stable memory module testers from CST. This translates to a higher return on their investment in their memory module production."

Inphi ICs Selected by CST for DDR Tester 2-2-2
The INCU877, part of Inphi's ExacTik Family of precision timing devices, is a high performance, low skew, PLL-based, zero delay buffer that distributes a differential input clock signal to ten differential clock outputs and one differential feedback (reference) clock output. The clock outputs are controlled by the input clock, the input feedback (reference) clock, the LVCMOS control inputs, and the analog power supply. A logic circuit on the clock input pins, independent from the input buffers, detects the logic low levels and places the part in a low power state where all the outputs and the PLL are off. The INCU877 also track Spread Spectrum Clocking (SSC) for reduced EMI. The INCU877 is designed for nominal 1.8V power supply operation and is packaged in a plastic 52-ball VFBGA.
