User's Guide SLLU160 – December 2011 SN65LVCP114 Evaluation Module (EVM) The Texas Instruments SN65LVCP114 Evaluation Module (EVM) board is used to evaluate the SN65LVCP114, 14.2Gbps Quad 1:2-2:1 Mux, Linear-Redriver with Signal Conditioning. This document provides guidance on the device's proper use by showing some operating configurations and test modes. The EVM board schematic and layout information are also provided for the customer.
www.ti.com WARNING This equipment is intended for use in a laboratory test environment only. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices, pursuant to subpart J, part 15 of FCC rules. These rules are designed to provide reasonable protection against radio frequency interference.

SN65LVCP114 EVM Board Configuration 4 www.ti.com SN65LVCP114 EVM Board Configuration The SN65LVCP114 is operated from a 2.5-V or 3.3-V power supply with a 1.0 A or greater current rating. The SN65LVCP114 has three ports; each port has four lanes. The switch logic of the SN65LVCP114 is implemented to support 2:1 MUX per lane, 1:2 DEMUX per lane, and independent lane switching. Each of the ports are independently programmed for receive equalization. The device also supports loopback on all three ports.
Test Setup www.ti.com Figure 2. SN65LVCP114 EVM Jumper Description 5 Test Setup The SN65LVCP114 EVM gives the developer two control interface options for operation, I2C or GPIO mode. Input and Output differential pairs are available through edge-launch SMAs with approximately 2.5 inches of trace with Rogers Low–Dielectric material with 0.1 µF AC Coupling capacitors. Power to the device, VCC, is applied using banana jacks (P1, P2). The USB-to-I2C circuitry on the board uses power from the USB 5-V signal.
