SY100S815ZH

Specialty Logic Overview

The SY100S815ZH is a low skew 1-to-4 PECL differential driver designed for clock distribution in high-performance systems. It accepts either a PECL clock input or a TTL input via the TEN pin. The device operates on a single +5V supply and features an internal 75kΩ PECL input pull-down resistor. It is available in a 16-pin SOIC package.

Specialty Logic Feature Summary

• Low skew design with guaranteed within-device skew specifications
• Selectable TTL or PECL clock input using the TEN enable pin
• Internal 75kΩ PECL input pull-down resistors

Specialty Logic Applications

• Clock distribution in high-performance PECL systems
• Quad PECL fanout buffering
• TTL to PECL conversion applications

Specialty Logic Procurement Notes

Verify the specific suffix ZH against official Microchip documentation, as standard datasheets list variants such as ZC, ZCTR, ZG, and ZGTR. Confirm RoHS compliance status and lead finish (Sn-Pb vs NiPdAu) based on the exact ordering code. Ensure the component meets industrial temperature ranges if required by your application.

Specialty Logic Selection Notes

Select this part when low skew is critical for clock distribution networks. It supports both PECL and TTL inputs through the TEN pin, offering flexibility in system design. The device requires a single +5V supply and includes internal pull-downs, simplifying interface requirements compared to other ECLinPS family members.

Specialty Logic Part Context

The SY100S815 belongs to the Precision Edge ECLinPS family from Micrel, now part of Microchip Technology. This series focuses on high-speed, low-skew clocking solutions. The S815 specifically provides a quad PECL output configuration, making it suitable for distributing clock signals to multiple destinations in synchronous digital systems.

Specialty Logic Replacement Considerations

Check for direct equivalents within the ECLinPS family. Verify that any substitute maintains the 16-pin SOIC footprint and supports the same voltage levels and skew specifications.
