NOTE(S):
(1)
CX28250 defaults to UTOPIA Level 2 when reset causing the TxClAv, RxClAv, RxSOC, and RxPrty signals to be in
high-impedance state. This may cause initialization problems for ATM layer UTOPIA Level 1 devices. Therefore, it is
recommended that pulldown resistors be used for these devices.

These pins are ground connections.
This pin is an ESD supply connection. If using this
device in a system with 5 V logic, this pin must be
connected to 5 V. If using in a 3.3 V system only,
connect to 3.3V.
