SY100E137JZ

Overview

The SY100E137JZ is an 8-bit binary ripple counter from the 100E series, housed in a 28-pin PLCC package. It operates with a minimum count frequency of 1.8 GHz and supports a supply voltage range of -4.2V to -5.5V. The device features differential clock inputs (CLK) and differential data outputs (Q0–Q7). Key control signals include asynchronous enable (A_Start), synchronous enables (EN1, EN2), and asynchronous master reset (MR). An internal VBB output provides a switching reference for single-ended operation.

Feature Summary

• Features very high-speed binary counting capabilities with optimized edge rates on the two least significant bits.
• Provides flexible control through both asynchronous and synchronous enable pins alongside an asynchronous master reset function.
• Includes an integrated VBB output pin designed to serve as a switching reference for single-ended clock input applications.

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the specific ordering suffix matches the required lead finish and packaging type. Ensure compatibility with existing system power supplies and signal levels before integration.

Selection Notes

Select this component when high-frequency binary counting is required within the ECLinPS voltage domain. Consider the trade-off between propagation delay across bit stages versus the need for precise timing control via synchronous or asynchronous enable inputs.

Part Context

This part belongs to the Microchip 100E family of high-speed logic devices. It functions as an 8-bit ripple counter utilizing differential signaling for improved noise immunity and speed performance compared to standard logic families.
