TLK1501: RX_ER debug help

Part Number: TLK1501

Hello team,

Could you please help me to debug RX_ER?

My TX side is set to TX_EN='0', TX_ER = '0' (Idle mode).

When sending the signal, RX side RX_DV, RX_ER, RXD[15..0] shows

unperiodical RX_DV='1' RX_ER='1' and RXD[15...0] received unintended data. (Indicated as red circle in the BD).

Also, When TX side is TX_EN='1' and TX_ER = '0' (Normal mode) and TXD[15..0] and

arbitary data is sent, RX_ER='1' and RXD[15..0] receives uninteded data.

Could you please help me to recieve the data without RX_ER correctly?

Please find internal link here for BD, schematic, and waveforms. (Please connect to VPN for download)

Regards,

Itoh
