SY100S314FC

Specialty Logic Overview

The SY100S314FC is a quint differential line receiver from the Synergy 300K family, designed for high-performance ECL systems. It features five differential inputs with emitter follower outputs and an extended supply voltage range of VEE = –4.2V to –5.5V. The device provides a maximum propagation delay of 900ps and transition times up to 900ps at +85°C. It includes a VBB output for single-ended use and achieves common mode rejection of +1.0V through active current sources. The component is housed in a 24-lead CERPACK (F24-1) package.

Specialty Logic Procurement Notes

Verify the specific ordering code SY100S314FC against the manufacturer's latest documentation to confirm the F24-1 package type and commercial operating range. Ensure that the power supply requirements align with the specified VEE range of –4.2V to –5.5V. Confirm compatibility with existing board layouts requiring a 24-lead CERPACK footprint before finalizing procurement decisions.

Specialty Logic Selection Notes

Select this component when designing systems requiring multiple differential receivers within a single ECL architecture. The device is suitable for applications needing extended supply voltage options and improved noise immunity through internal compensation. Consider the 24-lead CERPACK package constraints and ensure thermal management supports the specified operating temperature range for reliable performance.

Specialty Logic Part Context

This part belongs to the Synergy 300K family of ECL components manufactured by Micrel. It functions as a quint differential line receiver, offering pinout and functional compatibility with legacy Fairchild F100K devices. The series is engineered for high-speed digital applications where low propagation delay and robust signal integrity are critical requirements.

Specialty Logic Replacement Considerations

The SY100S314FC is functionally and pinout compatible with the Fairchild F100K. Designers replacing older designs should verify that the replacement meets the specific VEE voltage and timing requirements of the original system architecture.

Specialty Logic FAQ

How does the SY100S314 handle single-ended operation?

The device provides a VBB reference voltage output specifically for single-ended use. In this mode, the apparent input threshold of the true inputs is 30mV higher than that of the complementary inputs.

What is the common mode rejection capability of this receiver?

Common mode rejection of +1.0V is achieved through the use of active current sources within the circuit design.
