SY10EP33VZG

Overview

The SY10EP33VZG is a ÷4 PECL/LVPECL divider from the Precision Edge series, manufactured by Microchip Technology. It operates at guaranteed maximum frequencies exceeding 4GHz with propagation delays under 460ps across the industrial temperature range of -40°C to +85°C. The device supports both 3.3V and 5V power supply options and features an asynchronous reset pin for system synchronization. It includes internal 75kΩ input pull-down resistors and a VBB reference voltage output. The component is housed in an 8-pin SOIC package.

Feature Summary

• Integrated divide-by-4 clock divider function supporting high-frequency operation up to 4GHz
• Asynchronous reset capability allowing synchronous use of multiple dividers within a system
• Internal temperature compensation circuitry ensuring stable performance across wide operating temperatures
• Built-in VBB reference voltage output available for single-ended input biasing or AC-coupled input rebiasing

Applications

• High-speed clock distribution networks requiring frequency division
• Synchronization of multiple divider stages in complex timing systems
• Precision edge clock generation and conditioning circuits

Procurement Notes

Verify that the SY10EP33VZG suffix corresponds to the Industrial temperature range (-40°C to +85°C) and Pb-free NiPdAu finish as specified in the ordering information. Confirm the Z8-1 package type matches your PCB footprint requirements. Ensure design compatibility with the required VCC and VEE supply voltages before procurement.

Selection Notes

Select this component when a precise divide-by-4 function is required for PECL or LVPECL signals. Consider the internal VBB pin utility if single-ended inputs or AC-coupling are utilized in the design. Verify that the 8-pin SOIC package fits the assembly constraints and that the industrial temperature rating meets environmental specifications.

FAQ

How should the VBB pin be handled if single-ended inputs are used?

When using single-ended inputs, connect the unused differential input to the VBB pin to serve as a switching reference voltage. Decouple VBB to VCC via a 0.01µF capacitor and limit current sourcing or sinking to 0.5mA.

What is the function of the RESET pin?

The RESET pin is asynchronous and is asserted on the rising edge. It allows for the synchronous use of multiple EP33s in a system, overcoming the random state attained by internal flip-flops upon power-up.
