SY100S815ZC-TR

Specialty Logic Overview

The SY100S815ZC-TR is a low skew 1-to-4 PECL differential driver designed for clock distribution in high-performance systems. It accepts either a PECL or TTL input via the TEN pin. The device operates on a single +5V supply with internal 75kΩ pull-down resistors. Within-device skew is guaranteed at a maximum of 50 ps across commercial temperature ranges. Propagation delay from EIN to output ranges from 430 to 630 ps, while TIN delay ranges from 350 to 950 ps. Output rise/fall times are specified between 275 and 600 ps.

Specialty Logic Feature Summary

• Low skew design optimized for minimal gate-to-gate delay variation
• Selectable TTL or PECL clock input using the TEN enable pin
• Internal 75kΩ PECL input pull-down resistors
• Differential internal design with fully compatible PECL I/O

Specialty Logic Applications

• Clock distribution in high-performance PECL systems
• Quad PECL driver applications requiring low skew
• Systems utilizing ECLinPS family components

Specialty Logic Procurement Notes

Verify the specific ordering suffix ZCTR indicates tape and reel packaging. Confirm the ZC suffix corresponds to the commercial operating temperature range as defined in the manufacturer's ordering information. Ensure compatibility with the 16-pin SOIC package dimensions. Check for Pb-Free variants if required by environmental regulations, noting that the ZG suffix denotes industrial grade and Pb-free finish.

Specialty Logic Selection Notes

Select this component when low skew is critical for clock distribution networks. It supports both PECL and TTL inputs, offering flexibility in interface requirements. The device requires termination of differential outputs into 50 Ω to maintain skew specifications. Consider the commercial temperature range limits and single +5V supply requirement during system design.

Specialty Logic Part Context

This part belongs to the Precision Edge ECLinPS family from Micrel, Inc. It serves as the quad PECL version of the popular E111 driver. The device shares common processing with other family members, allowing for tighter control of propagation delay parameters through wafer characterization at the point of device personalization.
