Diodes Incorporated extends its passive multiplexer/demultiplexer(mux/demux) switches range with the introduction of PI2DBS16212A, a 4-to-2 differential channel switching IC with up to 20Gbps data rates. The new bidirectional devices are optimized to be in relation to insertion loss, return loss, skew, and crosstalk. The device offers -1.25dB insertion loss at 10GHz and has a return loss of -15db at 10GHz at a small footprint and low profile.


With 14GHz bandwidth, PI2DBS16212A offers minimal attenuation and has a bit-to-bit skew of just 10ps (maximum), a 20ps (maximum) channel-to-channel skew, a 50ps (maximum) propagation delay, and a -40dB (typical) differential crosstalk (depending on frequency). The strong signal integrity of the device makes it ideal for processing high-speed data signals such as those relating to PCIe 4.0, USB 3.2 Gen1, USB 3.2 Gen2, 10GE, Thunderbolt 3, SAS3.0, and SATA3.0.


The 1.8V, 200μA PI2DBS16212A, the best low-power alternative mux/demux switch can operate at a temperature range of -40°C to +85°C. The PI2DBS16212A is supplied in a 24-pin TQFN package (with 2.5mm x 2.5mm x 0.75mm dimensions) and has a unit price of $0.9 in 5000 piece quantities.
