We are using One TSEC of P1022 in RGMII mode. Should we provide 125MHz clock in TSEC1_GTX_CLK125 pin? What should be it's source - Oscillator or external @PHY recovered clock?</P><P>2. We are using serdes1 for on 2xPCIe and one SGMII and serdes2 disabled. We provided 100MHz in SD1_REF_CLK pin and SD2_REF_CLK is grounded. Is the scheme correct or do we need to provide clock in SD2_REF_CLK pins as well?</P></BODY></HTML> Wed, 27 Jan 2016 11:33:08 GMT https://community.nxp.com/t5/P-Series/Query-regarding-P1022-TSEC-GTX-clock-pin/m-p/468680#M2770 prasantahalder 2016-01-27T11:33:08Z Re: Query regarding P1022 TSEC GTX clock pin https://community.nxp.com/t5/P-Series/Query-regarding-P1022-TSEC-GTX-clock-pin/m-p/468681#M2771 <HTML><HEAD></HEAD><BODY><P>TSECn_GTX_CLK125 is the reference clock in RGMII mode.
