DS33Z11 Ethernet Mapper
7 of 169
1 DESCRIPTION
The DS33Z11 provides interconnection and mapping functionality between Ethernet Packet Systems and WAN
Time-Division Multiplexed (TDM) systems such as T1/E1/J1, HDSL, and T3/E3. The device is composed of a
10/100 Ethernet MAC, Packet Arbiter, Committed Information Rate controller (CIR), HDLC/X.86 (LAPS) mapper,
SDRAM interface, control ports, and bit error-rate tester (BERT). The packet interface consists of an Ethernet
interface using several physical-layer protocols. The Ethernet interface can be configured for 10 Mbps or 100
Mbps service. The DS33Z11 encapsulates Ethernet traffic with HDLC or X.86 (LAPS) to be transmitted over the
WAN interface. The WAN interface also receives encapsulated Ethernet packets and transmits the extracted
packets over the Ethernet port. The WAN physical interface supports a serial data stream up to 52 Mbps. The
WAN interface can be seamlessly connected to the Dallas Semiconductor/Maxim T1/E1/J1 framers, line interface
units (LIUs), and single-chip transceivers (SCTs). The WAN interface can also be seamlessly connected to the
Dallas Semiconductor/Maxim T3/E3/STS-1 framers, LIUs, and SCTs to provide T3, E3, and STS1 connectivity.
Refer to
Application Note 3411: DS33Z11—Ethernet LAN to Unframed T1/E1 WAN Bri
dge for an example of a
complete LAN to WAN solution.
The DS33Z11 is controlled through an 8-bit microcontroller port. A serial EEPROM (SPI) interface and hardware
mode are also included for applications without a host processor. The DS33Z11 has a 100MHz SDRAM controller
and interfaces to a 32-bit wide 128 Mbit SDRAM. The SDRAM is used to buffer the data from the Ethernet and
WAN ports for transport. The external SDRAM can accommodate up to 8192 frames with a maximum frame size
of 2016 bytes.
Operation without an external host simplifies and reduces the cost of typical applications such as connectivity to
T1/T3 and E1/E3 front ends. The DS33Z11 operates with a 1.8V core supply and 3.3V I/O supply.
