46.5.2 Features
Main features of RSDS transmitter are as follows
• Common Mode voltage between 0.5 V to 1.5 V
• Supports data rates upto 120 Mbps
• Output Impedence of 100  differential
• Programmable voltage swing
• Programmable option for controlling data polarity
• Programmable skew control
46.5.3 Data path signals
46.5.3.1 pad_p
This is the “positive” I/O signal connected bond pad for the RSDS output pad. The voltage supported by
the pad is defined by the VREF_RSDS and VSS associated with the cell.
