DESCRIPTION
■ 3.3V ±10% power supply
■ Guaranteed AC parameters over temperature:
f
MAX
> 275MHz (LVTTL)
■ < 2ns LVPECL-to-LVTTL propagation delay
■ < 600ps LVTTL-to-LVPECL propagation delay
■ Internal 75kΩ input pull-down resistors
■ Industrial temperature range: –40°C to +85°C
■ Available in 8-pin MSOP and SOIC packages
The SY10/100EPT28L is a differential LVPECL-to-
LVTTL translator and a LVTTL-to-differential LVPECL
translator in a single package. Because LVPECL (Positive
ECL) levels are used, only +3.3V and ground are required.
The small outline 8-pin package and the dual translation
design of the EPT28L makes it ideal for applications
which are sending and receiving signals across a
backplane.
The 100k series includes temperature compensation.
Thus, logic levels are constant over temperature.

Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for
extended periods may affect device reliability.
2. 10/100KEPT circuits are designed to meet the DC specifications shown in the above tables after thermal equilibrium has been established. The
circuit is in a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained.
3. Input and output parameters vary 1:1 with V
