Frequently Asked Questions
What is the maximum speed and jitter of this crosspoint switch?
It operates at 800 Mbps, achieving low power with a typical peak-to-peak jitter of 75 ps when using PRBS=2^-1 data patterns.
Does the DS90CP22 support different signal levels and standards?
Yes. It accepts LVDS signals and also supports LVPECL levels and interoperates with the ANSI/TIA/EIA-644-1995 LVDS standard.
How can I utilize the output channels for various distributions?
The device can be configured as a 2:1 mux, 1:2 demux, repeater, or 1:2 signal splitter, which is useful for fault-tolerant systems.
What are the recommended operating temperature and supply voltage ranges?
The operating temperature range is -40°C to +85°C. The supply voltage (Vcc) recommended by the manual is 3.0 V to 3.6 V.
