M21115/25 3.8 Gbps 20x20 / 40x40 Crosspoint Switch
> Product Overview
M21115 [3.8 Gbps 20x20] and M21125 [3.8 Gbps 40x40] Crosspoint Switch
The M21115/25 are 40/20 input by 40/20 output asynchronous crosspoint switches rated to operate up to 3.8
Gbps per lane. Its fully non-blocking switch core allows any input to be routed to any output, or any group of four
lanes to be routed to any other group of four lanes. The group of quad-lanes enables four lane applications with
stringent skew requirements, such as HDMI and DVI. This low-power design provides a flexible power supply
range, and the ability to power-off unused I/O. Additional power supply savings can be realized by utilizing the
SmartPowerTM feature, which dynamically powers-down unused portions of the switch core. Signal conditioning
capabilities include input equalization and output de-emphasis, configurable on a per-lane basis and optimized for
PCB traces and shielded twisted pair (STP) cables.
