DS10CP154
1.5 Gbps LVDS Crosspoint Switch
General Description
The DS10CP154 is a 1.5 Gbps 4x4 LVDS crosspoint switch
optimized for high-speed signal routing and switching over
FR-4 printed circuit board backplanes and balanced cables.
Fully differential signal paths ensure exceptional signal in-
tegrity and noise immunity. The non-blocking architecture
allows connections of any input to any output or outputs. The
switch configuration can be accomplished via external pins or
the System Management Bus (SMBus) interface. In addition,
the SMBus circuitry enables the loss of signal (LOS) monitors
that can inform a system of the presence of an open inputs
condition (e.g. disconnected cable).
Wide input common mode range allows the switch to accept
signals with LVDS, CML and LVPECL levels; the output levels
are LVDS. A very small package footprint requires a minimal
space on the board while the flow-through pinout allows easy
board layout. Each differential input and output is internally
terminated with a 100Ω resistor to lower device insertion and
return losses, reduce component count and further minimize
board space.
Features
■ DC - 1.5 Gbps low jitter, low skew, low power operation
■ Pin and SMBus configurable, fully differential, non-
blocking architecture
■ Wide input common mode range enables DC coupled
interface to CML or LVPECL drivers
■ LOS circuitry detects open inputs fault condition
■ On-chip 100 Ω input and output termination minimizes
insertion and return losses, reduces component count and
minimizes board space
■ 8 kV ESD on LVDS I/O pins protects adjoining
components
■ Small 6 mm x 6 mm 40-LLP space saving package
Applications
■ High-speed channel select applications
■ Clock and data buffering and muxing
■ SD / HD SDI Routers

Note 4: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions.
Note 5: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 6: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except VOD and
ΔVOD.
Note 7: Typical values represent most likely parametric norms for VCC = +3.3V and TA = +25°C, and at the Recommended Operation Conditions at the time of
product characterization and are not guaranteed.
Note 8: Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.
