MC100EP196BFAG

Overview

The MC100EP196BFAG is a 3.3 V ECL Programmable Delay Chip (PDC) designed for clock deskewing and timing adjustment. It provides variable delay of differential NECL/PECL input transitions with a digitally selectable resolution of approximately 10 ps and a net range up to 10.4 ns. The device features an FTUNE pin for analog fine-tuning, adding 0 to 60 ps of delay. It operates within a supply voltage range of 3.0 V to 3.6 V in PECL mode or -3.0 V to -3.6 V in NECL mode. The maximum input clock frequency exceeds 1.2 GHz typical. The component is housed in a 32-lead LQFP package.

Feature Summary

• Programmable delay matrix with 10 ps digital increments and analog FTUNE fine-tuning capability
• Supports multiple input logic levels including LVPECL, LVNECL, LVDS, LVCMOS, and LVTTL via configurable reference pins
• Internal cascade architecture allows chaining multiple units for extended programmable delay ranges without external gating

Applications

• Multi-channel high-speed signal deskewing and timing alignment
• Precision measurement of unknown high-speed device delays using D-flip-flop correlation
• Clock distribution systems requiring low-jitter programmable delay adjustments

Procurement Notes

Verify the ordering suffix FA indicates the LQFP-32 package variant distinct from the MN QFN-32 version. Confirm RoHS compliance and Pb-Free status as specified in the datasheet. Ensure power supply connections to all VCC and VEE pins are established to guarantee proper operation. Check moisture sensitivity level requirements for storage and handling procedures.

Selection Notes

Select this component when precise sub-nanosecond delay tuning is required for differential ECL signals. The FTUNE pin enables resolution finer than the 10 ps digital step, suitable for applications demanding tight skew tolerances. Consider cascading capabilities if the total delay requirement exceeds the single-chip 10.4 ns range. Verify interface compatibility with LVCMOS, LVTTL, or ECL control logic through appropriate VCF and VEF pin configurations.

Part Context

The MC100EP196B belongs to onsemi's 100 Series ECL family, which includes temperature compensation. It shares architectural similarities with the EP195 but adds the FTUNE analog tunability feature. The BFAG suffix specifically denotes the Lead-Free LQFP-32 packaging option, distinguishing it from other package variants like the QFN-32.

Replacement Considerations

MC100EP196BMNG offers identical electrical functionality but utilizes a QFN-32 package instead of LQFP-32. Direct substitution requires verifying footprint compatibility and thermal management differences between the two package types.
