GND
s VBB output
s Available in 8-pin MSOP and SOIC package
The SY100EPT21L is a single differential LVPECL-to-
LVTTL translator using a single +3.3V power supply.
Because LVPECL (Low Voltage Positive ECL) levels are
used, only +3.3V and ground are required. The small
outline 8-lead SOIC package and low skew single gate
design make the EPT21L ideal for applications that
require the translation of a clock or data signal where
minimal space, low power, and low cost are critical.
VBB allows a differential, single-ended, or AC-coupled
interface to the device. If used, the VBB output should be
bypassed to VCC with 0.01µF capacitor.
Under open input conditions, the /D will be biased at a
VCC/2 voltage level and the D input will be pulled to
ground. This condition will force the Q output low to
provide added stability.
The 100EPT is compatible with positive ECL 100K
logic levels.
