SAN FRANCISCO Programmable logic supplier Lattice Semiconductor Corp. Monday (Dec. 5) released the ispClock 5600A second-generation family of enhanced zero-delay clock generators.
Lattice (Hillsboro, Ore.) said the first of these products, the ispClock5620A, is a programmable, E2CMOS-based device capable of generating up to 20 clock outputs, each with independently programmable output skew, input/output standard and frequency selection. The non-volatile, in-system programmable ispClock5600A devices are pin compatible with Lattice's first generation ispClock5600 devices, but provide a number of significant additional features and parametric enhancements, the company said.
Lattice said the maximum voltage-controlled oscillator operating frequency of the ispClock5600A devices has been increased to 800 megahertz, supporting the generation of popular clock frequencies simultaneously from a single master frequency. The input clock frequency range has been extended from five to 400 MHz to enable support at 8.192 MHz, a popular telecom clock frequency, according to Lattice.
"Traditionally, as the performance requirements of the system increased, the effort required to generate and distribute clocks grew exponentially," said Stan Kopec, Lattice corporate vice president of marketing, in a statement. "Our programmable ispClock5600A devices provide unprecedented convenience to designers without compromising the system specifications. The devices provide faster time-to-market, reduced board space and improved manufacturability and reliability."
Pricing on the ispClock5620A starts at $6.80 per unit in quantities of 10,000 or more. Evaluation kits also are available through authorized Lattice distributors or on the Lattice Web site for $295.
