SY100S815ZC

Specialty Logic Overview

The SY100S815ZC 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 internal 75kΩ PECL input pull-down resistors. Within-device skew is guaranteed at a maximum of 50 ps across temperatures from 0°C to +85°C. Propagation delay ranges from 330 ps to 950 ps depending on the input source. It is housed in a 16-pin SOIC package.

Specialty Logic Feature Summary

• Low skew design optimized for minimal gate-to-gate skew within the device
• Selectable TTL or PECL clock input controlled by the TEN enable pin
• Differential internal design with fully compatible PECL I/O
• Integrated 75kΩ PECL input pull-down resistors

Specialty Logic Applications

• Clock distribution in high-performance PECL systems
• Quad PECL buffering applications
• Systems requiring selectable TTL or PECL clock inputs

Specialty Logic Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm that the specific ordering suffix matches the required lead finish and operating temperature range. Ensure proper termination of differential outputs into 50 ohms to maintain specified skew performance during installation.

Specialty Logic Selection Notes

Select this component when low skew is critical for system timing integrity. Verify compatibility between the chosen input source (TTL vs. PECL) and the TEN pin configuration. Ensure the application environment remains within the commercial temperature range of 0°C to +85°C for valid parameter guarantees.

Specialty Logic Part Context

This part belongs to the Precision Edge family, sharing common processing with other ECLinPS members. This shared manufacturing allows for tighter control over parameters like propagation delay through wafer characterization at the point of device personalization.

Specialty Logic Replacement Considerations

Specialty Logic FAQ

How does the TEN pin affect input selection?

When the TEN pin is HIGH, the TTL input is enabled and the PECL input is disabled. When set LOW, the TTL input is disabled and the PECL input is enabled.

What are the termination requirements for the outputs?

Both sides of the differential output must be terminated into 50 ohms to ensure the skew specification is met, even if only one side is being used.
