SN75LVCP601EVM

User's Guide SLLU211 – October 2014 LVCP601 Evaluation Module The SN75LVCP601 is a dual channel, single lane SATA redriver and signal conditioner supporting data rates up to 6.0Gbps. The device complies with SATA physical link 2m and 3i specifications. The SN75LVCP601 handles interconnect losses at both its input and output. The input stage of each channel offers selectable equalization settings that can be programmed to match loss in the channel. The differential outputs provide selectable de-emphasis to compensate for the anticipated distortion the SATA signal will experience. Level of equalization and de-emphasis settings depend on the length of interconnect and its characteristics. Both equalization and de-emphasis levels are controlled by the setting of signal control pins EQ1, EQ2 and DE1, DE2. This evaluation module acts as a reference design that can be easily modified for any intended application. Target applications include notebooks, desktops, docking stations, servers, and work stations. Schematics and layout information are included at the end of this user's guide. Figure 1.

This guide describes the construction and usage of the EVM for the LVCP601 which is meant to serve as an evaluation tool for the LVCP601, as well as be used as a reference design for the device. 2 LVCP601 Evaluation Module Configuration Kit Contents: This EVM kit should contain the following items: • LVCP601 EVM board • This user’s manual This board is designed to facilitate easy evaluation of the LVCP601 using internal SATA connectors. Physical switches allow for simple configuration of the equalization, de-emphasis, and operation mode settings of the LVCP601. The EVM board has two internal SATA connectors, one for the host side and one for the device side of the redriver. This module also runs on a 3-V supply voltage that is derived from the standard SATA power connection. The configuration of the equalization, de-emphasis, de-emphasis width, and standby mode settings are all selected using SW1-SW7. See Table 1 for further details about the configuration of the EVM. Suggested default configuration settings for the EVM can be found in Table 2. Table 1.

The board consists of a signal layer on top, a ground layer, a power layer, and another signal layer on the bottom. The impedance of the differential traces is 100 ohms. Other traces have an impedance of 50 ohms. NOTE: In order to achieve the desired impedance, it is recommended that you consult your board manufacturer for their process and design requirements.
