DS33X41+

Specialized Overview

The DS33X41+ is a specialized Ethernet over PDH mapping device designed to extend 10/100/1000Mbps Ethernet LAN segments by encapsulating MAC frames in GFP-F, HDLC, cHDLC, or X.86 (LAPS) for transmission over PDH/TDM data streams. It features one Ethernet port and one TDM serial port within a 256-ball CSBGA package. The device supports VCAT/LCAS link aggregation for up to 16 links and operates on 1.8V, 2.5V, and 3.3V supplies.

Specialized Feature Summary

• Supports IEEE 802.3 MAC with Autonegotiation and Flow Control
• Provides Quality of Service (QoS) including VLAN, Q-in-Q, 802.1p, and DSCP support
• Enables dynamic link aggregation via VCAT/LCAS for up to 16 links
• Includes traffic shaping through CIR/CBS policing and external DDR SDRAM buffer management

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 and errata documentation before integration, as multiple revisions may be available. Confirm lead-free/RoHS compliance requirements match the '+ ' suffix designation. Ensure the design accommodates the specified industrial temperature range of -40°C to +85°C.

Specialized Selection Notes

Select this component when a single Ethernet interface and a single TDM serial port are required for EoPDH applications. Compare against the DS33X42+ if two TDM ports are needed, or the DS33X11+ for lower port density requirements. Verify that the 256-ball CSBGA package fits the board layout constraints.

Specialized Part Context

This device belongs to the DS33X162 family of semiconductor devices, which includes variants like the DS33X161+, DS33X82+, and DS33W41+. The family shares common encapsulation protocols and QoS features but differs in port counts and voice capabilities.
