8.3.4
This section describes the SGMII transmit and receive AC timing specifications. Transmitter and receiver
characteristics are measured at the transmitter outputs (SD2_TX[n] and SD2_TX[n]) or at the receiver
inputs (SD2_RX[n] and SD2_RX[n]) as depicted in

Notes:
1. Measured at receiver.
2. Each UI is 800 ps ± 100 ppm.
3. The external AC coupling capacitor is required. It is recommended to be placed near the device transmitter outputs.
4. See RapidIO 1x/4x LP Serial Physical Layer Specification for interpretation of jitter specifications.
