SN55LVCP22中文资料QML class Q 2×2 1-Gbps LVDS crosspoint switch数据手册TI规格书

描述 Description

The SN55LVCP22 is a 2×2 crosspoint switch providing greater than 1000 Mbps operation for each path. The dual channels incorporate wide common-mode (0 V to 4 V) receivers, allowing for the receipt of LVDS, LVPECL, and CML signals. The dual outputs are LVDS drivers to provide low-power, low-EMI, high-speed operation. The SN55LVCP22 provides a single device supporting 2:2 buffering (repeating), 1:2 splitting, 2:1 multiplexing, 2×2 switching, and LVPECL/CML to LVDS level translation on each channel. The flexible operation of the SN55LVCP22 provides a single device to support the redundant serial bus transmission needs (working and protection switching cards) of fault-tolerant switch systems found in optical networking, wireless infrastructure, and data communications systems.

The SN55LVCP22 uses a fully differential data path to ensure low-noise generation, fast switching times, low pulse width distortion, and low jitter. Output channel-to- channel skew is 80 ps (typ) to ensure accurate alignment of outputs in all applications.
