SN75LVCP422中文资料2 通道 SATA 3Gbps 转接驱动器数据手册TI规格书

描述 Description

The SN75LVCP422 is a dual channel, single lane SATA redriver and signal conditioner supporting data rates up to 3 Gbps. The device complies with SATA specification revision 2.6 and eSATA requirements. The SN75LVCP422 operates from a single 3.3-V supply. Integrated 100- line termination and self-biasing make the device suitable for AC coupling. The inputs incorporate an OOB detector, which automatically turns the differential outputs off while maintaining a stable output common-mode voltage compliant to SATA link. The device is also designed to handle SSC transmission per SATA spec.The SN75LVCP422 handles interconnect losses at both its input and output. The built-in transmitter pre-emphasis feature is capable of applying 0 dB or 2.5 dB of relative amplification at higher frequencies to counter the expected interconnect loss. On the receive side the device applies a fixed equalization of 7 dB to boost input frequencies near 1.5 GHz. Collectively, the input equalization and output pre-emphasis features of the device work to fully restore SATA signal integrity over extended cable and backplane pathways.The device is hot-plug capable

preventing device damage under device hot-insertion such as async signal plug/removal, unpowered plug/removal, powered plug/removal, or surprise plug/removal.
