MC10EL32DTG

Counter Dividers Overview

The MC10EL32DTG is an integrated ÷2 divider from onsemi, housed in a SOIC-8NB package. It supports PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) and NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). The device features a maximum toggle frequency of 3.0 GHz and a propagation delay of 510 ps. It includes an internally generated VBB reference voltage for single-ended or AC-coupled interfaces, asynchronous reset functionality, and internal input pulldown resistors on CLK and R pins.

Counter Dividers Feature Summary

• Supports differential, single-ended, or AC coupled clock inputs via the dedicated VBB pin
• Provides asynchronous reset capability for system synchronization upon power-up
• Includes internal input pulldown resistors on clock and reset lines to stabilize open inputs

Counter Dividers Applications

• Clock signal division in high-speed digital systems
• Frequency synthesis circuits requiring precise timing references
• Synchronization of multiple divider stages within complex logic architectures

Counter Dividers Procurement Notes

Verify the specific suffix 'DTG' against official ordering information, as standard listings typically specify 'DG' (Tube) or 'DR2G' (Tape & Reel). Confirm package type and RoHS compliance status directly with the manufacturer. Ensure design requirements align with the specified PECL/NECL voltage ranges and thermal characteristics before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a high-speed ÷2 divider with flexible interface options is required. The inclusion of the VBB pin allows adaptation for single-ended sources without external biasing networks. Consider the 100 series variant if temperature compensation is necessary for operation across extreme environmental conditions.

Counter Dividers Part Context

This part belongs to the MC10EL/100EL family of ECL dividers manufactured by onsemi. It serves as a fundamental building block for clock distribution networks, offering faster performance compared to legacy E131 equivalents. The device is designed for applications demanding low jitter and high toggle frequencies within standard ECL logic families.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended input is not used?

When the VBB pin is not utilized for single-ended or AC-coupled interfacing, it must be left open.

What is the behavior of the internal flip-flop during power-up?

Upon power-up, the internal flip-flop attains a random state; the reset pin must be asserted to synchronize the device.
