Procurement Notes

Verify that the ordering suffix matches the required package type and lead finish specifications. Confirm the operating temperature range aligns with the industrial grade requirements. Ensure compatibility with ECL Pro logic families during integration. Cross-reference the manufacturer part number against official distributor databases to validate authenticity and current availability status.

Selection Notes

Select this component when a high-frequency divide-by-four function is required within PECL or LVPECL architectures. The inclusion of an internal VBB pin simplifies AC-coupled input biasing compared to standard dividers. Consider the 8-pin MSOP package for space-constrained designs requiring surface-mount assembly capabilities.

Part Context

This device belongs to the Precision Edge EP33 family, designed for high-performance clock applications. The 100K series variant incorporates internal temperature compensation circuitry to maintain stable electrical characteristics across varying thermal conditions. It represents a specialized solution for differential clock signal processing.

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 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 asserted on the rising edge. It allows for the synchronous use of multiple EP33 devices in a system by resetting internal flip-flops upon power-up.
