MC100EP196BMNR4G

Overview

The MC100EP196BMNR4G is a 3.3 V ECL Programmable Delay Chip 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 (PECL) or -3.0 V to -3.6 V (NECL), supporting maximum input clock frequencies exceeding 1.2 GHz typical.

Feature Summary

• Programmable delay matrix with 10 ps digital increments and analog FTUNE fine-tuning capability
• Supports cascading multiple units via D10 control pins to extend programmable range
• Accepts LVPECL, LVNECL, and LVDS input signal levels with configurable threshold logic
• Includes internal temperature compensation and dedicated VBB reference voltage output

Applications

• Multi-channel deskewing in high-speed systems to match impedance and cable length variations
• Precision measurement of unknown high-speed device delays using dual-chip configurations
• Timing adjustment in automated test equipment requiring sub-nanosecond resolution

Procurement Notes

Verify the ordering suffix MN corresponds to the QFN-32 package and NR4G indicates tape and reel shipping format. Confirm RoHS compliance and lead-free status as specified in the datasheet attributes. Ensure power supply connections for all VCC and VEE pins are externally connected to guarantee proper operation during validation.

Selection Notes

Select this component when precise clock deskewing or timing alignment is required in ECL-based architectures. Consider the cascading feature if delays exceeding 10.4 ns are necessary. Verify that the input signal levels (LVPECL/LVDS) match the interface requirements and that the operating temperature range of -40°C to +85°C suits the application environment.

Part Context

The MC100EP196B belongs to the ON Semiconductor 100 Series ECL family, which includes temperature-compensated programmable delay chips. It shares architectural similarities with the EP195 but adds FTUNE tunability. The series is designed for high-frequency applications requiring deterministic delay adjustments without external gating components.
