SY10EL16VFZC

Overview

The SY10EL16VFZC is an enhanced differential receiver manufactured by Microchip Technology, originally designed by Micrel. It operates with 3.3V and 5V power supply options and features a propagation delay of 250ps. The device includes data synchronous Enable/Disable (/EN) functionality for glitchless gating of the QHG and /QHG outputs. It provides D and /D inputs rather than a VBB output, making it suitable for crystal oscillator applications where timing signals require precise gating.

Feature Summary

• Data synchronous Enable/Disable (/EN) input provides complete glitchless gating of the high-gain outputs (QHG and /QHG).
• Features very high voltage gain compared to standard EL16 or EL16V devices, with DC gain several times larger on QHG outputs.
• Includes internal 75kΩ input pull-down resistors for stable operation.
• Designed as a complete solution for high-quality, high-frequency crystal oscillator applications.

Applications

• Pulse Amplifier applications
• Limiting Amplifier applications
• Gating timing signals
• High frequency crystal oscillator circuits

Procurement Notes

Verify the specific package type and lead finish when ordering. The 'Z' suffix indicates an 8-pin SOIC package. Confirm whether tape and reel packaging is required by checking for the 'TR' suffix in the part number. Ensure compatibility with the intended operating temperature range and power supply voltages before procurement.

Selection Notes

Select this component when glitchless gating of differential clock signals is required without adding extra counts to the output. It is suitable for designs needing high voltage gain and synchronous enable control. Compare against SY10EL16VC if a VBB reference output is preferred over differential data inputs.

Part Context

This device belongs to the SY10/100EL16VA-VF series of enhanced differential receivers. It shares identical pinouts with previous generations like the SY10EL16V but offers improved capabilities such as higher DC gain and synchronous enable features. It is available in commercial and industrial temperature ranges within 8-pin packages.

Replacement Considerations

SY10EL16VCZC serves as a similar alternative within the same family, differing primarily in the provision of a VBB output instead of differential data inputs. Verify pinout compatibility and functional requirements regarding the enable signal behavior before substitution.

FAQ

How does the /EN input affect the QHG and /QHG outputs?

When the /EN signal is LOW, the input is passed to the outputs. When HIGH, it forces the QHG LOW and /QHG HIGH on the next negative transition of the data input, providing glitchless gating.

What is the difference between the Q and QHG outputs?

The QHG and /QHG outputs have a DC gain several times larger than the DC gain of the standard Q and /Q outputs.
