4:1 Multiplexer for up to 43 Gb/s

The MX4140 is a 4:1 high-speed Multiplexer for data rates up to 43 Gb/s. Key features are:

• single-ended and differential I/O operation,
• broadband operation,
• adjustable output swing,
• scaleable architecture (e.g. 16:1 MUX),
• single supply voltage.

At the data inputs, the MX4140 consists of four symmetrical buffers which allow for single-ended as well as differential drive. Furthermore the input buffers provide a high input sensitivity of 50 mVpp (single-ended).
The same holds for the clock input, which runs at half of the frequency of the output data rate (so called half-rate clocking: e.g. 20 GHz clock for 40 Gb/s output data rate). This allows to use reasonably priced RF-synthesizers in the 26.5 GHz band for pattern generation in the 40 Gb/s range.
