SY100EL52
5V ECL Differential Data and Clock D Flip-Flop
Features
General Description
•
•
•
•
The SY100EL52 is a differential data, differential clock
D flip-flop. Data enters the master portion of the flip-flop
when the clock is low and is transferred to the slave,
then the outputs, upon a positive transition of the clock.
The differential clock inputs also allow the EL52 to be
used as a negative edge triggered device.
365 ps Propagation Delay (typical)
2.8 GHz Toggle Frequency (typical)
Internal 75 kΩ Input Pull-Down Resistors
Available in 8-Lead SOIC Package
The EL52 employs input clamping circuitry so that,
under open input conditions (pulled down to VEE), the
outputs of the device will remain stable.

Devices are designed to meet the DC specifications shown in the above table after thermal equilibration
has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse
airflow greater than 500 lfpm is maintained.
Outputs are terminated through a 50Ω resistor to VCC – 2.0V.
The CMR range is referenced to the most positive side of the differential input voltage. Normal operation is
obtained if the high level falls within the specified range and the peak-to-peak voltage lies between
150 mV and 1V.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
