• The maximum supported SDR frequency is 200 MHz which is covered in HS200 mode, and the maximum DDR frequency is

200 MHz as a part of HS400 mode.

uSDHC3 supports up to SDR104 (200 MHz) on primary SD3_* pins, but when it is multiplexing on GPIO_IO[27:22], below are the

modes supported:

• eMMC High Speed DDR, High Speed SDR, and less than or equal to 26 MHz MMC legacy protocols are supported.

• SDR50 (100 MHz) and SDR104 (200 MHz) modes are NOT supported.

• eMMC HS400 and HS200 modes are NOT supported

• The maximum supported SDR and DDR frequency is 50 and 52 MHz

If IO is supplied by 3.3 V, the maximum supported SDR/DDR frequency is 50/52 MHz

4.12.2 Ethernet controller (ENET) AC electrical specifications

Ethernet supports the following key features:

• Support ENET AVB

• Support IEEE 1588

• Support Energy Efficient Ethernet (EEE)

• 1.8 V/3.3 V RMII operation, 1.8 V RGMII operation

The following sections introduce the ENET AC electrical specifications.

4.12.2.1 ENET2 signal mapping

The following timing specs are defined at the chip I/O pin and must be translated appropriately to arrive at timing specs/constraints

for the physical interface.
