Overview
The MC100EP33D, produced by onsemi, is an integrated B4 divider designed for high-speed applications. This device features differential clock inputs and is available in various package types, including SOIC-8, TSSOP-8, and DFN8. The MC100EP33D is part of the 100 Series, which includes temperature compensation, ensuring stable operation across a range of temperatures.
The device is versatile, operating in both PECL (Positive ECL) and NECL (Negative ECL) modes. It provides an internally generated voltage supply (VBB) that can be used as a switching reference voltage or to rebias AC coupled inputs. The reset pin is asynchronous and allows for the synchronization of multiple devices in a system.

Q & A
- What is the maximum frequency of operation for the MC100EP33D?
The MC100EP33D operates at frequencies greater than 4 GHz typical.
- 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.
- What is the propagation delay of the MC100EP33D?
The propagation delay is 320 ps.
- How should the VBB pin be used?
The VBB pin can be used as a switching reference voltage or to rebias AC coupled inputs. It should be decoupled with VCC via a 0.01 μF capacitor and limited to ±0.5 mA current sourcing or sinking.
- What is the purpose of the reset pin?
The reset pin is asynchronous and allows for the synchronization of multiple devices in a system by resetting the internal flip-flops on the rising edge.
- What are the storage and operating temperature ranges?
The storage temperature range is -65°C to +150°C, and the operating temperature range is -40°C to +85°C.
- Are Pb-Free packages available for the MC100EP33D?
- What is the default state of the Q output when inputs are open or at VEE?
The Q output will default LOW when inputs are open or at VEE.
- What types of packages are available for the MC100EP33D?
The device is available in SOIC-8, TSSOP-8, and DFN8 packages.
- Does the MC100EP33D have safety features on its inputs?
