MC10EP451FAR2G

Flip Flops Overview

The MC10EP451FAR2G is a 6-bit fully differential D-type register from the onsemi 10EP series, designed for very high-frequency applications. It features a common clock and single-ended Master Reset (MR). The device operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE from -3.0 V to -5.5 V. Key electrical parameters include a typical propagation delay of 430 ps, a maximum operating frequency of 3 GHz, and a quiescent supply current of up to 125 mA. It utilizes a 32-lead LQFP package.

Flip Flops Feature Summary

• Fully differential 6-bit register with asynchronous Master Reset
• Internal 75 kΩ pulldown resistors on all inputs; unused inputs default LOW
• Safety clamp protection on differential inputs
• Low skew: 20 ps within-device and 35 ps device-to-device

Flip Flops Applications

• High-speed data path registration
• Clock distribution networks
• Serial-to-parallel conversion logic
• Telecommunications equipment requiring ECL compatibility

Flip Flops Procurement Notes

Verify that the specific ordering suffix 'R2G' corresponds to the Tape & Reel packaging configuration as defined in the manufacturer's documentation. Confirm RoHS compliance status and Pb-Free designation requirements for the target assembly process. Ensure the procurement channel provides valid traceability for the 32-LQFP component variant.

Flip Flops Selection Notes

Select this component when a registered differential data path with a global reset function is required at frequencies up to 3 GHz. The 10EP series offers lower power consumption compared to the 100EP series while maintaining similar speed characteristics. Ensure the design supports the necessary negative voltage supply for NECL operation or appropriate termination for PECL if using positive supply configurations.

Flip Flops Part Context

This part belongs to the MC10/100EP451 family of ECL registers. The '10' prefix indicates the standard power/speed grade, distinct from the '100' series which typically offers higher drive strength or different thermal characteristics. The F suffix denotes the LQFP-32 package, while the R2G suffix specifies the reel packaging format for automated assembly.

Flip Flops Replacement Considerations

MC10EP451FAG serves as a tube-packaged alternative within the same functional family. MC100EP451 variants offer equivalent functionality but may differ in power consumption and thermal specifications due to the 100EP series classification.

Flip Flops FAQ

What is the default state of unused differential inputs?

Unused differential register inputs can be left open and will default to a LOW state due to internal 75 kΩ pulldown resisters.

How does the device handle input voltage ranges for PECL and NECL modes?

In PECL mode, VCC ranges from 3.0 V to 5.5 V with VEE at 0 V. In NECL mode, VCC is 0 V and VEE ranges from -3.0 V to -5.5 V.

What are the skew specifications for this register?

The device exhibits a typical skew of 20 ps within the device and 35 ps between devices under identical transition conditions.
