MC100EP195BFAG

Overview

The MC100EP195BFAG is a 3.3 V ECL Programmable Delay Chip (PDC) designed for clock deskewing and timing adjustment in high-speed systems. It provides variable delay of differential NECL/PECL input transitions with a digitally selectable resolution of approximately 10 ps and a net programmable range up to 10.2 ns. The device features a maximum input clock frequency exceeding 1.2 GHz and operates within a supply voltage range of 3.0 V to 3.6 V for PECL mode, or -3.0 V to -3.6 V for NECL mode. It includes internal temperature compensation and supports cascading multiple units via the D10 control pin to extend the total delay range. The component is housed in an LQFP-32 package.

Feature Summary

• Provides precise programmable delay adjustment with 10 ps resolution for clock deskewing applications
• Supports cascading architecture using D10 control pins to expand total delay range across multiple devices
• Accepts LVPECL, LVNECL, and LVDS input signal levels with flexible threshold control options
• Includes internal VBB reference voltage output for single-ended input configurations

Applications

• Multi-channel deskewing to eliminate timing skews caused by impedance or cable length differences
• Measuring unknown high-speed device delays by correlating programmed delay values with flip-flop outputs
• Timing adjustment in high-speed digital data systems requiring fine-tuned synchronization

Procurement Notes

Verify the specific ordering suffix 'FAG' corresponds to the LQFP-32 package configuration as defined in the manufacturer's ordering information. Confirm that the procurement source provides the official datasheet revision Rev. 4 documentation to ensure accurate electrical parameter alignment. Check for lead time requirements associated with the tray packaging format specified for this suffix variant.

Selection Notes

Select the MC100EP195BFAG when an LQFP-32 surface mount package is required for the programmable delay function. Ensure the design accommodates the necessary power supply rails for either PECL (+3.3V) or NECL (-3.3V) operation modes. Verify that the system requires the specific 10-bit address bus interface for delay selection and that the thermal resistance characteristics of the LQFP package meet the application's heat dissipation needs.

Part Context

This component belongs to the MC100EP195B series of 3.3 V ECL Programmable Delay Chips. The BFAG suffix specifically denotes the LQFP-32 package variant, distinguishing it from the QFN32 package version designated by the MNG suffix. Both variants share identical electrical specifications and functional capabilities, differing only in physical footprint and pinout arrangement.

Replacement Considerations

The MC100EP195BMNG serves as a direct package alternative offering identical electrical performance in a QFN32 footprint. Designers must account for the mechanical differences between LQFP-32 and QFN32 packages during PCB layout modifications.
