DS33X162+

Specialized Overview

The DS33X162+ is an Ethernet over PDH mapping device that encapsulates MAC frames in GFP-F, HDLC, cHDLC, or X.86 for transmission over TDM data streams. It supports 10/100/1000Mbps Ethernet LAN segments with VCAT/LCAS link aggregation across up to 16 links. The component features two Ethernet ports and sixteen serial ports, utilizing a 256-ball CSBGA package. Operating voltages include 1.8V, 2.5V, and 3.3V supplies.

Specialized Feature Summary

• Supports dynamic link aggregation via VCAT/LCAS for up to 16 links
• Performs store-and-forward frame processing at wire speed
• Provides programmable classification, priority queuing, and traffic shaping
• Enables external processor extraction and insertion of OAM flows

Specialized Applications

• Bonded Transparent LAN Service
• LAN Extension
• Ethernet Delivery Over T1/E1/J1, T3/E3, OC-1/EC-1, G.SHDSL, or HDSL2/4

Specialized Procurement Notes

Verify the specific revision status before procurement, as multiple revisions may be available through various sales channels. Check official errata documentation for any deviations from published specifications. Confirm lead-free/RoHS compliance requirements match the + suffix designation. Ensure the 256-ball CSBGA footprint aligns with board layout constraints.

Specialized Selection Notes

Select this model when sixteen serial ports are required for high-density EoPDH applications. Compare against the DS33X161+ if only one Ethernet port is needed. Verify compatibility with external DDR SDRAM buffers for packet storage. Ensure the design accommodates the specified industrial temperature range of -40°C to +85°C.

Specialized Part Context

This device belongs to the DS33X family of semiconductor devices designed for extending Ethernet LAN segments over PDH/TDM networks. It serves as a specialized interface solution for delivering Ethernet Access Services, including eLINE and VLAN, by mapping MAC frames into synchronous interconnect streams.

Specialized Replacement Considerations

Public confirmed substitute part numbers: DS33X161+, DS33X82+, DS33X81+, DS33X42+, DS33X41+, DS33X11+. These variants share the same encapsulation technology but differ in port counts and pin configurations.
