Introduction
The Texas Instruments (TI) SN65LVCP114 is a 14.2Gbps asynchronous, protocol-agnostic, low-latency
QUAD 1:2-2:1 mux, linear-redriver switch with signal conditioning. The device linearly compensates for
channel loss in backplane and active-cable applications. The architecture of the SN65LVCP114 crosspoint
switch is designed to work effectively with ASIC or FPGA products implementing digital equalization by
using decision feedback equalizer (DFE) technology. SN65LVCP114 mux, linear-redriver switch preserves
the integrity (composition) of the received signal ensuring optimum DFE and system performance.
SN65LVCP114 provides low-power mux, linear-redriver solution while at the same time extending the
effectiveness of DFE.

EVM PCB and High-Speed Design Considerations
The EVM and the contents of this guide are used to evaluate device parameters in addition to helping with
high-speed board layout. As the frequency of operation increases, the board designer must take special
care to ensure that the highest signal integrity is maintained. To achieve this, the board's impedance is
controlled to 50
Ω
single-ended or 100
Ω
differential impedance for both the low and high-speed
differential serial and clock connections. The use of vias is minimized and, when necessary, are designed
to minimize impedance discontinuities along the transmission line. Care was taken to control trace length
mismatch (board skew) to less than
±
0.1 MIL.
The board layout is designed and optimized to support high-speed operation. Understanding impedance
control and transmission line effects is crucial when designing high-speed boards. Some of the advanced
features offered by this board include:
•
SN65LVCP114 printed circuit board (PCB) designed for optimal high-speed signal integrity using
Rogers Material for the outer signal layers and FR-4 for the inner layers. All Gigabit signals are routed
over the Rogers Material for minimal signal loss.
•
SMA and header fixtures are easily connected to test equipment.
•
All input/output signals are accessible for rapid prototyping.
•
On-board capacitors provide AC coupling of high-speed transmit and receive signals.
