SY100EP195VTI

Overview

The SY100EP195VTI is a programmable delay line manufactured by Microchip Technology in a 32-lead TQFP package. It provides a delay range from approximately 2.1 ns to 10.8 ns with 10 ps increments controlled via a 10-bit digital register. The device supports PECL mode (VCC = 3.0V to 5.5V, VEE = 0V) and NECL mode (VCC = 0V, VEE = –3.0V to –5.5V). Maximum operating frequency exceeds 1.6 GHz. Propagation delay ranges from 1650 ps to 2750 ps depending on the setting and temperature. Supply current is typically 150 mA to 175 mA.

Feature Summary

• Pin-for-pin compatible with ON Semiconductor MC100EP195
• Supports cascading for extended delay ranges using internal circuitry
• Accepts ECL, CMOS, or TTL control signals
• Includes safety clamps on inputs

Applications

• Clock de-skewing
• Timing adjustment
• Aperture centering

Procurement Notes

Verify the specific suffix 'TI' against official documentation to confirm tape-and-reel packaging status. Confirm RoHS compliance details directly with the manufacturer. Ensure the component meets the required ambient temperature range of -40°C to +85°C for your application environment.

Selection Notes

Select this component when precise programmable delay between 2.1 ns and 10.8 ns is required. It is suitable for systems needing up to 1.6 GHz signal processing. Consider cascading multiple units if delays exceeding 10.8 ns are necessary. Verify interface compatibility with PECL, LVPECL, NECL, or LVECL input standards.

Part Context

This part belongs to the SY100EP series of high-speed programmable delay lines. It serves as a direct replacement for legacy Micrel/ON Semiconductor devices like the MC100EP195. The device is designed for high-frequency timing applications requiring fine resolution adjustments.

FAQ

How does the /EN pin affect the output?

When /EN is active low, Q/Q outputs the delayed IN/IN signal. When inactive high, the inputs are gated, forcing Q/Q to a differential logic low state.

What is the function of the Dc pin?

The Dc pin acts as an eleventh control bit that enables cascading multiple SY100EP195V devices to extend the total delay range available.

Can the device accept single-ended inputs?

Yes, by connecting the unused input of the differential pair to the VBB pin, which biases the input appropriately for single-ended PECL signals.
