FINAL
DESCRIPTION
The SY10/100EL16VA-VF are differential receivers.
The devices are equivalent to SY10/100EL16 or SY10/
100EL16V with enhanced capabilities. The Q
HG
, /Q
HG
outputs have a DC gain several times larger than the DC
gain of the Q output.
The SY10/100EL16VA have an identical pinout to the
SY10/100EL16 or SY10/100EL16V. It provides a V
BB
output for either single-ended application or as a DC
bias for AC coupling to the device.
The SY10/100EL16VB are very similar to the SY10/
100EL16VA. The /Q output is provided for feedback
purposes.
The SY10/100EL16VC provides an /EN input which is
synchronized with the data input (D) signal in a way that
provides glitchless gating of the Q
HG
and /Q
HG
outputs. When
the /EN signal is LOW, the input is passed to the outputs and
the data output equals the data input. When the data input is
HIGH and the /EN goes HIGH, it will force the Q
HG
LOW and
the /Q
HG
HIGH on the next negative transition of the data
input. If the data input is LOW when the /EN goes HIGH, the
next data transition to a HIGH is ignored and Q
HG
remains
LOW and /Q
HG
remains HIGH. The next positive transition of
the data input is not passed on to the data outputs under these
conditions. The Q
HG
and /Q
HG
outputs remain in their dis-
abled state as long as the /EN input is held HIGH. The /EN
input has no influence on the /Q output and the data input is
passed on (inverted) to this output whether /EN is HIGH or
LOW. This configuration is ideal for crystal oscillator applica-
tions, where the oscillator can be free running and gated on
and off synchronously without adding extra counts to the
output.
The SY10/100EL16VD provides the flexibility of all the
combinations in DIE form, in 16-pin 150mil SOIC package or
in 10-pin MSOP package. The 16-pin SOIC and 10-pin MSOP
packages are ideal for prototyping DIE applications.
The SY10/100EL16VE are similar to the SY10/100EL16VB
where the Q, /Q output is made available differently. In this
package option, V
BB
is no longer provided.
The SY10/100EL16VF are similar to the SY10/100EL16VC,
offering the D, /D inputs rather than the V
BB
output.

NOTES:
1. Duty cycle skew is the difference between a t
PLH
and t
PHL
propagation delay through a device.
2. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of
≈
40 to Q, /Q outputs and a DC gain of
≈
200 or higher to
/Q
HG
/Q
HG
outputs.
3. 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. Note for PECL operation, the V
CMR
(min) will be fixed at 3.3V – |V
CMR
(min)|.
4. Parametric values specified at: 10/100EL16VA-VF Series:
-3.0V to -5.5V.
