Overview
The MC100EP451FAG is a 6-bit fully differential register produced by onsemi, designed for very high frequency applications where a registered data path is necessary. This component features a common clock and a single-ended Master Reset (MR), making it ideal for high-performance logic systems, particularly in test systems. The register includes internal 75k-ohm pulldown resistors on all inputs and an override clamp on differential inputs to ensure default states when inputs are left open or forced below a certain voltage threshold.

Q & A
- What is the primary function of the MC100EP451FAG?
The MC100EP451FAG is a 6-bit fully differential register with a common clock and single-ended Master Reset, designed for high-frequency applications.
- What are the typical propagation delay and maximum frequency of the MC100EP451FAG?
The typical propagation delay is 450 ps, and the maximum frequency is greater than 3.0 GHz.
- What is the effect of the Master Reset (MR) on the MC100EP451FAG?
When the Master Reset (MR) is set HIGH, it asynchronously resets all registers, forcing the Q outputs to go LOW.
- How do unused differential register inputs behave on the MC100EP451FAG?
Unused differential register inputs can be left open and will default to a LOW state due to the internal 75k-ohm pulldown resistors and safety clamp.
- What are the operating voltage ranges for PECL and NECL modes?
For PECL mode, VCC = 3.0 V to 5.5 V with VEE = 0 V. For NECL mode, VCC = 0 V with VEE = -3.0 V to -5.5 V.
- Is the MC100EP451FAG RoHS compliant and Pb-free?
- What is the skew within and between devices for the MC100EP451FAG?
The skew within the device is 20 ps, and the skew between devices is 35 ps.
- What type of package is the MC100EP451FAG available in?
The MC100EP451FAG is available in an LQFP-32 package.
- What is the moisture sensitivity level (MSL) of the MC100EP451FAG?
The MSL of the MC100EP451FAG is Level 2.
- Where can I find more detailed technical information about the MC100EP451FAG?
You can find detailed technical information in the datasheet available on the onsemi website or through other authorized distributors like Mouser Electronics.
