Introduction
The Texas Instruments (TI) SN65LVCP1414 is a 14.2-Gbps quad channel dual mode linear-redriver with
signal conditioning. The device linearly compensates for channel loss in backplane and active-cable
applications. The architecture of SN65LVCP1414 linear-redriver is designed to work effectively with ASIC
or FPGA products implementing digital equalization using decision feedback equalizer (DFE) technology.
SN65LVCP1414 preserves the integrity (composition) of the received signal ensuring optimum DFE and
system performance. SN65LVCP1414 provides a low power linear-redriver solution while at the same time
extending the effectiveness of DFE.

EVM PCB and High-Speed Design Considerations
Use the EVM and the contents of this guide to evaluate device parameters in addition to helping with high-
speed board layout. As the frequency of operation increases, special care is required to ensure that the
highest signal integrity is maintained. Achieve this by controlling the board's impedance to 50

differential. 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 ±0.001 in.

Overall, the board layout is designed and optimized for high-speed operation. Thus, understanding
impedance control and transmission line effects are crucial when designing high-speed boards. Some of
the advanced features offered by this board include:
