1.
The DS33X162 family of devices provide interconnection and mapping functionality between Ethernet Systems and
WAN Time-Division Multiplexed (TDM) systems such as T1/E1/J1, HDSL, T3/E3, and SONET/SDH. The device is
composed of up to two 10/100/1000 Ethernet MACs, up to 16 Serial Ports, a Arbiter, GFP-F /HDLC/cHDLC/X.86
(LAPS) Mappers, a DDR SDRAM interface, and control ports. Ethernet traffic is encapsulated with GFP-F, HDLC,
cHDLC, or X.86 (LAPS) to be transmitted over the WAN Serial Interfaces. The WAN Serial Interfaces also receive
encapsulated Ethernet frames and transmit the extracted frames over the Ethernet ports. The LAN frame interface
consists of Ethernet interfaces using one of two physical layer protocols. It can be configured with up to two
10/100Mbps MII/RMII ports or a single GbE GMII port. The WAN Serial Interface can be configured for up to eight
serial data streams at up to 52Mbps each, or 16 serial data streams at up to 2.5Mbps each. The Serial Interfaces
can be seamlessly connected to the Maxim T1/E1/J1 Framers, Line Interface Units (LIUs), and Single-Chip
Transceivers (SCTs). The WAN interfaces can also be seamlessly connected to the Maxim T3/E3/STS-1 Framers,
LIUs, and SCTs to provide T3, E3, or STS1 connectivity.
Microprocessor control can be accomplished through a 8-bit Micro controller port or SPI Bus. The device has a
125MHz DDR SDRAM controller and interfaces to a 32-bit wide 256Mb DDR SDRAM via a 16-bit data bus. The
DDR SDRAM is used to buffer data from the Ethernet and WAN ports for transport.
The power supplies consist of a 1.8V core supply, a 2.5V DDR SDRAM supply, and 3.3V I/O supply. The DDR
interface also requires a 1.25V reference voltage that can be obtained through a resistor-divider network.
