MC100EP33MNR4G

Counter Dividers Overview

The MC100EP33MNR4G is a ÷4 integrated clock divider from the onsemi 100 Series, designed for high-speed ECL applications. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from −3.0 V to −5.5 V (VCC = 0 V). The device features a typical propagation delay of 320 ps and supports maximum frequencies exceeding 4 GHz. It includes an asynchronous reset pin asserted on the rising edge, internal temperature compensation, and a dedicated VBB reference voltage output. The component is housed in a DFN8 package.

Counter Dividers Feature Summary

• Integrated ÷4 frequency division capability with differential clock inputs
• Asynchronous reset functionality allowing system synchronization upon power-up
• Internal VBB reference voltage generation for single-ended input biasing
• Temperature-compensated design ensuring stable performance across operating ranges

Counter Dividers Applications

• High-speed clock distribution networks requiring precise frequency division
• Synchronization circuits for multi-device systems utilizing asynchronous reset
• PECL and NECL logic interface designs operating at frequencies above 4 GHz

Counter Dividers Procurement Notes

Verify the specific ordering suffix MNR4G corresponds to the DFN8 package configuration as listed in the official datasheet. Confirm RoHS compliance status and lead times directly with authorized distributors or onsemi representatives, as availability may vary. Ensure proper thermal management for the exposed pad in the DFN8 package during assembly.

Counter Dividers Selection Notes

Select this component when a low-skew ÷4 divider is required within ECL-based architectures. The 100 Series offers improved AC performance compared to standard ECL counterparts. Consider the DFN8 package for compact board layouts, noting its thermal requirements. Verify that the supply voltage range aligns with either PECL or NECL system specifications before integration.

Counter Dividers Part Context

This device belongs to the MC10/100EP33 family, which provides integrated ÷4 division functions. The 100 Series variant typically exhibits faster AC characteristics than the 10 Series. It shares functional similarities with other ECL dividers but distinguishes itself through specific timing parameters and the inclusion of a dedicated VBB pin for input conditioning.

Counter Dividers FAQ

How does the VBB pin function in single-ended input conditions?

The VBB pin provides an internally generated reference voltage. For single-ended inputs, unused differential inputs should be connected to VBB to serve as a switching reference voltage.

What is the behavior of the Q outputs when inputs are open?

When inputs are left open or at VEE, the Q outputs will default to a LOW state due to internal safety clamps and pull-down resistors.
