Various customization options relating to transmitter and receiver elastic buffer control and behaviors are presented in this collapsible section. Click the title to expand the section.
• Receiver elastic buffer bypass mode . When the receiver elastic buffer is bypassed and two or more transceiver channels are enabled, specify whether multi-lane buffer bypass mode or single-lane buffer bypass mode is used. When multi-lane mode is selected, the designated receiver master channel acts as the buffer bypass master lane and clock source for the one receiver user clocking network helper block instance that provides user clocks to the master and all slave lanes. When single-lane mode is selected, each transceiver channel receiver elastic buffer is bypassed individually, resulting in an instance of the receiver buffer bypass controller helper block and an instance of the receiver user clocking network helper block for each transceiver channel. The default is multi-lane mode.
