Pericom Semiconductor's PI2LVD512 is a 10- to 5-channel
multiplexer/demultiplexer Switch. The device multiplexes
differential signals to one of two corresponding outputs. The
switch is bidirectional. It is designed for low bit-to-bit skew, high
channel-to-channel noise isolation and is compatible with various
differential standards such as LVDS
5 different channels, 2:1 Mux/DeMux
LVDS signal switching beyond 2.5Gbps
Low bit-to-bit skew, 8ps
Low crosstalk: -70dB @ 10MHz
Switching speed: 4ns
VCC Operating Range: +1.5V to +2.0V
ESD: Data bits @ 8kV HBM, select bits @ 2kV HBM
Packaging (Pb-free & Green):
- 64-pin TSSOP (A)

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 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.
