Hi,
Our customer's application is planning to use TLK106 with AM335x processor
and we are confused with the RMII reference clock for TLK in RMII mode.
In case of RMII mode the TLK106 datasheet mentions that 50MHz ±50ppm clock source should be
connected to the Clock Interface(XI) and it also mentions that a 50MHz clock through the RX_CLK pin is
required to synchronize the RXD[1:0], CRS_DV,RX_DV and RX_ER pins.
But due to AM335x eratta it cannot produce "REF_CLK" so it should be provided from the PHY itself.
note :We could have used TLK110 which has CLKOUT feature, but it is not recommended according to this post.
In case of TLK106 could you please let me know if the below connection would be proper?
should we use a CMOS clock source instead of a crystall oscillator?
Best Regards
Prad
