Electrical Characteristics
When operating in SGMII mode, the eTSEC EC_GTX_CLK125 clock is not required for this port. Instead, SerDes reference
clock is required on SD2_REF_CLK and SD2_REF_CLK pins.
2.9.3.1
The characteristics and DC requirements of the separate SerDes reference clock are described in
Serial Interfaces.”
2.9.3.2
This table lists the SGMII SerDes reference clock AC requirements. Please note that SD2_REF_CLK and SD2_REF_CLK are
not intended to be used with, and should not be clocked by, a spread spectrum clock source.
Notes:
1. 8 ns applies only when 125 MHz SerDes2 reference clock frequency is selected via cfg_srds_sgmii_refclk during POR.
2. In a frequency band from 150 kHz to 15 MHz, at BER of 10E-12.
3. Total peak-to-peak deterministic jitter “Dj” should be less than or equal to 50 ps.
