DS33ZH11

Specialized Overview

The DS33ZH11 is a specialized Ethernet Mapper integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It extends a 10/100 Ethernet LAN segment by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over PDH/TDM data streams. The device supports bidirectional-synchronous interconnect up to 52Mbps over interfaces such as xDSL, T1/E1/J1, T3/E3, V.35/Optical, OC-1/EC-1, and SONET/SDH Tributary. It operates with a 1.8V supply and features 3.3V tolerant I/O. The component is housed in a 100-ball CSBGA package measuring 10mm x 10mm and functions within a temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports 10/100 IEEE 802.3 Ethernet MAC with MII and RMII interfaces
• Provides 52Mbps synchronous TDM serial port with independent transmit and receive timing
• Includes HDLC/LAPS encapsulation with programmable FCS and interframe fill
• Operates in hardware/SPI mode without requiring a host processor

Specialized Applications

• 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 ordering suffix against official documentation to confirm package type and functional configuration. Confirm that the procurement channel provides valid traceability for this discontinued component. Ensure environmental compliance certifications match the required project specifications before finalizing acquisition.

Specialized Selection Notes

Select the DS33ZH11 when a compact solution is required for Ethernet-to-TDM bridging without host processor overhead. This model is specifically designed for hardware or SPI mode-only operation. Compare it against the DS33Z11 if external SDRAM buffering or parallel microprocessor interface capabilities are necessary for the design.

Specialized Part Context

The DS33ZH11 belongs to the DS33Z11 family of Ethernet Mappers. It shares the same core functionality but utilizes a smaller 100-ball CSBGA package compared to the standard 169-ball version. This variant is optimized for applications where board space is limited and complex processor integration is not desired.

Specialized Replacement Considerations
