SY10E137JC

Overview

The SY10E137JC is an 8-bit binary ripple counter from the 10E series, manufactured by Microchip Technology. It operates with a minimum count frequency of 1.8 GHz and supports an extended VEE supply range of –4.2V to –5.5V. The device features differential clock inputs and data outputs, asynchronous enable (A_Start), synchronous enables (EN1, EN2), and an asynchronous Master Reset (MR). It is housed in a 28-pin PLCC package.

Feature Summary

• Features very high-speed binary counting capabilities with optimized edge rates for the two least significant bits to support frequencies up to 1.8 GHz.
• Provides flexible control through both asynchronous and synchronous enable pins, allowing precise management of counting states.
• Includes an internal switching reference output (VBB) designed to facilitate single-ended clock input configurations.

Applications

• Multiple frequency clock generation
• Counters in high-performance ATE time measurement boards

Procurement Notes

Verify that the specific ordering suffix matches the required lead finish and packaging format. The JC designation indicates a commercial operating temperature range and a standard Sn-Pb lead finish. Confirm compatibility with existing board layouts requiring a 28-pin PLCC footprint before procurement.

Selection Notes

Select this component when designing systems requiring high-frequency binary division or counting within ECLinPS logic families. Ensure the design accommodates the –4.2V to –5.5V power supply requirements and utilizes differential signaling for optimal performance at speeds exceeding 1.8 GHz.

Part Context

This part belongs to the 10E series of high-speed ECL components produced by Micrel, now part of Microchip Technology. The series is engineered for demanding applications where signal integrity and propagation delay are critical constraints in digital circuit design.
