The SY89206V and SY89216V are differential PECL/
ECL receiver/buffers in a space-saving (2mm
2mm)
MLFTM package. The devices are functionally equivalent
to the SY10/100EL16V, but feature a 70% smaller
footprint.
The SY89206/216V provide a V
BB
output for either
single-ended use or as a DC bias for AC-coupling to the
device. The V
BB
pin should be used only as a bias for
the SY89206/16V as its current sink/source capability is
limited. Whenever used, the V
BB
pin should be bypassed
with a 0.01
F capacitor to V
CC
.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.

Note 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.
Note 2.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
Note 3.
Package Thermal Resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB.

Note 6.
Duty cycle skew is the difference between a t
PLH
and t
PHL
propagation delay through a device.
Note 7.
Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of
40V/V.
Note 8.
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. The lower end of the CMR range varies 1:1 with V
EE
. The numbers
in the specification table assume a nominal V
EE
= 3.3V. Note for PECL operation, the V
CMR
(min) will be fixed at 3.3V |V
CMR
(min)|.
