Issue Date:
June 2003
The SY89307V is a differential receiver with a variable
output swing. It is functionally equivalent to the
SY100EP16VS but in an ultra-small 8-lead MLFTM package
that features a 70% smaller footprint. Like the EP16VS its
variable output swing makes it ideal for use as a VCSEL
laser driver.
The operational range of the SY89307V control input is
from V
BB
(maximum output swing) to V
CC
(minimum output
swing). The output swing can be controlled by a variable
resistor between the V
BB
pin and V
CC
with the wiper driving
V
CTRL
.
The SY89307V provides 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 this device
as its current sink/source capability is limited. Whenever
used, the V
BB
pin should be bypassed to V
CC
via a 0.01
F
capacitor.
Under open input conditions the Q output will be 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.
Due to the limited drive capability use for input of the same package only.
Note 4.
Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB.

Note 5.
Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of
40 when output has a full swing.
Note 6.
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 spec table assume a nominal V
EE
= 3.3V and V
CC
= 0V. Note for PECL operation, the V
CMR
(min.) will be fixed at
3.3V |V
CMR
(min.)|.
Note 7.
Output at full swing.
