3.0 Applications
This chapter provides details of the CX28250 reference design. The
CX28250-CX28236 Evaluation Module (EVM) is an ATM over SONET Network
Interface Card reference design. The main components of the design are the
CX28250 (ATM-PHY) and the CX28236 (ATM-SAR) from Mindspeed.

CX28236 has a PCI interface that allows the host to control the device. Control
for the CX28250 is provided through the PHY interface of the CX28236 and does
not require glue logic.
