4. Technical Information
The transmit and receive signals on the OSS-HIB25-x16 are driven and conditioned by Pericom redriver chips. Adjustments can be
made to equalization, de-emphasis and output swing. These controls are factory set by the use of zero Ohm resistors. In the
following tables a 0 indicates that a zero Ohm resistor has been installed and a 1 indicates no resistor. In rare cases, mostly where
non-OSS equipment is used with the HIB25-x16, these adjustments may need to be changed. The following tables are made
available for this purpose. It is highly recommended to contact OSS customer support before making changes to these settings.
