SY10EL33ZG-TR

Overview

The SY10EL33ZG-TR is a 3.3V ECL ÷4 divider manufactured by Microchip Technology in an 8-Lead SOIC package. It operates within a temperature range of –40°C to +85°C and features a typical toggle frequency of 4.2 GHz with a typical propagation delay of 640ps. The device supports differential, single-ended, or AC-coupled clock inputs via CLK and /CLK pins, and includes an asynchronous Reset pin. It provides differential data outputs at Q and /Q, along with an internal VBB reference voltage output for input biasing.

Feature Summary

• Integrated ÷4 divider functionality supporting differential, single-ended, and AC-coupled interfaces
• Internal 75 kΩ input pull-down resistors and dedicated VBB reference voltage output
• Asynchronous Reset pin asserted on the rising edge for system synchronization

Applications

• Clock signal division in high-speed digital systems
• Frequency synthesis and distribution networks
• Synchronization of multiple divider stages in complex timing architectures

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging configuration containing 1,000 units per reel. Confirm the 'ZG' designation indicates the Pb-Free NiPdAu finish and the industrial temperature range of –40°C to +85°C. Ensure compatibility with the 8-Lead SOIC (Z8-1) physical footprint during procurement planning.

Selection Notes

Select this component when a precise ÷4 division ratio is required for 3.3V ECL or PECL applications. The device is suitable for designs needing high bandwidth output transitions and guaranteed propagation delay specifications across the full industrial temperature range. Consider the availability of the VBB pin for biasing external AC-coupled circuits if single-ended inputs are utilized.

Part Context

This part belongs to the SY100EL33L family of integrated dividers produced by Microchip Technology. It is designed as a replacement for legacy Micrel devices, specifically superseding older SY10EL33 versions. The product line focuses on providing high-frequency clock division capabilities with robust electrical characteristics for demanding telecommunications and networking environments.

FAQ

How should the VBB pin be handled if not used for input biasing?

If the VBB output is not used to bias AC-coupled inputs, it should be left open.

What is the behavior of the internal flip-flops upon power-up?

Upon power-up, the internal flip-flops attain a random state; the Reset input must be used to synchronize them.
