Description

Pericom Semiconductor’s PI2DBS212 is an 1:2 differential

channel multiplexer/demultiplexer switch. Using a specialized

design scheme, Pericom has been able to achieve a performance

of 3Gbps data rate mux/de-mux function. Due to its bi-direction-

al nature, the PI2DBS212 can be used to allocate bandwidth to

two different locations as a demux, or connect two high-speed

sources to a single receiver as a mux.

The PI2DBS212 will target the following standards: SAS, SATA

I, SATA II, XAUI, INFINIBAND, HYPERTRANSPORT, and

RAP ID I/O, for application in computers, consumer electronics,

instrumentation, etc.

Notes:

1. CL = Load capacitance: includes jig and probe capacitance.

2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator

3. Output 1 is for an output with internal conditions such that the output is low except when disabled by the output control.

output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.

4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.

5. The outputs are measured one at a time with one transition per measurement.
