to-LVPECL translator. The device receives standard PECL
signals and translates them to differential LVPECL output
signals (or vice versa). SY100EL92 can also be used as a
differential line receiver for PECL-to-PECL or LVPECL-to-
LVPECL signals. However, please note that for the latter
we will need two different power supplies. Please refer to
Function Table for more details.
V
BB
outputs are provided for interfacing single ended
input signals. If a single ended input is to be used, the V
BB
output should be connected to the D input and the active
signal will drive the D input. When used, the V
BB
should be
bypassed to V
CC
via a 0.01µF capacitor. The V
BB
is
designed to act as a switching reference for the SY100EL92
under single ended input conditions. As a result, the pin
can only source/sink 0.5mA of current.
To accomplish the PECL-to-LVPECL level translation,
the SY100EL92 requires three power rails. The V
CC
and
V
CC
_V
BB
supply is to be connected to the standard PECL
supply, the 3.3V supply is to be connected to the V
CCO
supply, and GND is connected to the system ground plane.
Both the V
CC
and V
CCO
should be bypassed to ground with
a 0.01µF capacitor.
To accomplish the LVPECL-to-PECL level translation,
the SY100EL92 requires three power rails as well. The 5.0V
supply is connected to the V
CC
and V
CCO
pins, 3.3V supply
is connected to the V
CC
_V
BB
pin and GND is connected to
the system ground plane. V
CC
_V
BB
is used to provide a
proper V
BB
output level if a single ended input is used. For
differential LVPECL input V
CC
_V
BB
can be either 3.3V or
5V.
Under open input conditions, the D input will be biased
at a V
CC
/2 voltage level and the D input will be pulled to
GND. This condition will force the "Q" output low, ensuring
stability.

Notes:
1. Power supply requirements applies as indicated in the DC electrical characteristics tables.
2. Skew is measured between outputs under identical transitions.
3. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device Common Mode Range.
4. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ~40.
5. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified
range and the peak-to-peak voltage lies between V
PP
min. and 1V.
