MPC837xE-RDS, Rev. 1.0
16 Freescale Semiconductor
Preliminary, Subject to Change without Notice
MPC837xE-RDS Board
2.1.8 SATA Controller
MPC837xE has a SATA controller for storage applications as shown in Figure 7. There are two SATA
channels for MPC8377E. It requires a 100-MHz input clock, which is provided by the clock generator.
2.1.9 PCI Express Interface (PCI-E & Mini PCI-E)
MPC8377E supports the PCI Express (PCI-E) interface. It can be configured as two mini PCI-E interfaces
or one mini PCI-E interface and one 1X PCI-E interface as shown in Figure 7. It also requires a 100-MHz
input clock, which is provided by the clock generator.

2.1.10 10/100/1000 BaseT Interface
On the MPC837xE-RDS board, eTSEC1 and eTSEC2 use RGMII mode. The eTSEC1 and eTSEC2 drive
two on-board 10/100/1000 PHYs (RTL8211B), respectively. The I/O voltage is set to 3.3 V RGMII for
RTL8211B. The RGMII (1000 BaseT) is a source synchronous bus. For a transmit bus connection, it is
synchronous to GTX_CLK from the TSEC module. The receive bus connection is synchronous to
RX_CLK generated from the PHY device. The MPC837xE MII management interface also connects to
