ON Semiconductor Introduces Precise ECL Timing Delay Chip For High-Frequency Clock Management.

PHOENIX--(BUSINESS WIRE)--Oct. 28, 2002

MC100EP196 offers unparalleled PECL/NECL delay-programmability for

clock management within high-performance test, instrumentation and

networking applications

Extending its presence in the high-performance clock- and data-management arena, ON Semiconductor (Nasdaq:ONNN) today introduced the MC100EP196 -- an Emitter Coupled Logic (ECL) programmable delay chip with a secondary tuning input for clock de-skew in networking systems, pattern generation, and pulse and data formatting in test and instrumentation equipment.

As semiconductor components move toward higher frequencies, the current level of precision of standard delay devices is insufficient for controlling the timing signals in advanced networking systems. Designers now struggle with the skew between timing signals that is created by topological differences in circuit board as the period of signal arrival decreases. Test-and-measurement of these high-performance systems also demand equipment capable of near-ideal signals at a much higher frequency. The MC100EP196 addresses these critical design needs.

At operating frequencies greater than 1.2 gigahertz (GHz), the MC100EP196 offers the same high performance of the MC100EP195 -- a 3.3 volt (V), 5 V ECL programmable delay chip -- with delay timings between 2.2 and 12.2 nanoseconds (ns) in 10 picoseconds (ps) units. A fine tune (FTUNE) input feature added to the MCP100EP196 delivers supplementary delay programmability between 0 ps and 60 ps to address the increased accuracy required by the latest high-speed applications. This expanded programmability eliminates the need to re-spin, re-assemble and re-test circuit boards if the timing signals do not match.

The MC100EP196 accepts ECL, Complimentary Metal Oxide Semiconductor (CMOS) and Transistor-Transistor Logic (TTL). This provides system designers with the ability to directly program the MC100EP196 from a micro-controller, thus eliminating the need for specific programming circuitry.

The MC100EP196 is compatible with both positively- and negatively-referenced low voltage 3.0 V to 3.6 V system supplies in PECL or NECL mode respectively. Required delay is selected by the 10 programmable data select inputs D(0:9) that are latched in place by a high-signal on the latch enable (LEN) control. ON Semiconductor that increases the programmable range even further by offering the MC100EP196 with an additional pin for cascading multiple devices..

"The overall performance and versatility of the MC100EP196 provides an ideal way to overcome three primary design hurdles," said Mike Radhanauth, ON Semiconductor market development director for High Frequency Products. "With the MC100EP16, systems designers can effectively de-skew incongruent clock signals, perfect the generation of test pulses and format Automated Test Equipment (ATE) data."

Packaging and Price

Packaged in a space-saving standard 32-pin Low Profile Quad Flat Pack (LQFP), ON Semiconductor offers the MC100EP196 for $9.40 per unit in 10,000 unit quantities. The device is also available in wafer form for designers requiring additional design flexibility.
