FEATURES
DESCRIPTION
ꢀ 425ps propagation delay
The SY10EL1189 is a differential receiver, differential
transmitter specifically designed to drive coaxial cables.
It incorporates the output cable driver capability of the
SY10EL89 Coaxial Cable Driver with additional circuitry
to multiplex the output cable drive source between the
cable receiver or the local transmitter inputs. The
multiplexer control circuitry is TTL compatible for ease of
operation.
ꢀ 1.6V output swings
ꢀ Single +5V operation
ꢀ Internal 75KΩ input pull-down resistors
ꢀ Available in 16-pin SOIC package
The SY10EL1189 is useful as a bypass element for
Fibre Channel-Arbitrated Loop (FC-AL) or Serial Storage
Architecture (SSA) applications, to create loop style
interconnects with fault tolerant, active switches at each
device node. This device is particularly useful for back
panel applications where small size is desirable.
LOGIC DIAGRAM
From Input Cable
(ECL Levels)
The EL89 style drive circuitry produces swings twice
as large as a standard PECL output. When driving a
coaxial cable, proper termination is required at both ends
of the line to minimize reflections. The 1.6V output swings
allow for proper termination at both ends of the cable.
Because of the larger output swings, the QT, QT outputs
are terminated into the thevenin equivalent of 50Ω to
VCC-3.0V instead of 50Ω to VCC-2.0V.

test socket or mounted on a printed circuit board and transverse air greater than 500lfm is maintained.
2. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the differential
output signals.
3. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.
4. Duty cycle skew is the difference between tPLH and tPHL propagation delay through a device.
5. Minimum input swing for which AC parameters are guaranteed.
