SY10EL33LZI-TR

Overview

The SY10EL33LZI-TR is a 3.3V ECL ÷4 divider manufactured by Microchip Technology in an 8-pin SOIC package. It operates with a power supply voltage of 3.0V to 3.8V and supports toggle frequencies up to 4.2 GHz. The device features a typical propagation delay of 640ps from clock to output and includes internal 75kΩ input pull-down resistors. It provides differential data outputs (Q, /Q) and accepts differential or single-ended clock inputs.

Feature Summary

• Integrated ÷4 divider functionality supporting PECL and NECL modes
• Asynchronous reset pin for system synchronization
• Internal reference voltage output (VBB) for biasing applications
• High bandwidth output transitions with guaranteed propagation delay

Applications

• Clock signal division in high-speed digital systems
• Frequency synthesis circuits requiring precise timing
• Differential logic interface translation and distribution

Procurement Notes

Verify the specific ordering suffix 'ZG' indicates the industrial temperature range (-40°C to +85°C) and Pb-free NiPdAu termination as documented in the product identification system. Confirm that the 'TR' suffix corresponds to the tape and reel packaging configuration containing 1,000 units per reel before finalizing procurement orders.

Selection Notes

Select this component when a dedicated ÷4 divider is required for PECL or NECL logic families operating at 3.3V. Ensure the application can accommodate the 8-pin SOIC footprint and that the maximum toggle frequency requirement does not exceed 4.2 GHz. Consider the asynchronous nature of the reset function during system design.

Part Context

This part belongs to the SY10/100EL33L family of integrated dividers designed for high-frequency clock management. It succeeds earlier versions like the SY10EL33 and SY100EL33, which have been removed from the datasheet revision history. The device utilizes Precision Edge technology to ensure fast switching speeds and low skew characteristics.

FAQ

How should the VBB pin be utilized?

The VBB pin provides an internally generated reference voltage output. If used for input bias, it must be bypassed to ground with a 0.01µF capacitor. It has limited current sink and source capability.

What is the behavior of the Reset pin upon power-up?

Upon power-up, the internal flip-flops attain a random state. The Reset pin is asynchronous and is asserted on the rising edge to allow for the synchronization of multiple devices in a system.
