Analog Devices Inc./Maxim Integrated DS33Z11+UNUSED

Overview

DS33Z11+UNUSED from Maxim Integrated is a demonstration and evaluation kit for the DS33Z11 Ethernet transport-over-serial link device, integrating an on-board DP83848 Ethernet PHY, DS2155 T1/E1 transceiver, DS3170 T3/E3 transceiver, transformers, BNC and RJ48 network interfaces, and MMC2107 processor. It supports T1, E1, T3, and E3 serial line rates with hardware/software configuration modes and real-time register access via ChipView software.

For engineers reviewing the DS33Z11+UNUSED datasheet, DS33Z11+UNUSED pinout, DS33Z11+UNUSED application, or DS33Z11+UNUSED equivalent, this kit enables rapid validation of Ethernet-to-TDM bridging in telecom infrastructure, protocol conversion testing, and register-level debugging of DS33Z11, DS2155, and DS3170 devices under live traffic conditions.

Technical Context

The DS33Z11+UNUSED demo kit implements a complete Ethernet-to-serial transport system using the DS33Z11 as the core framing and encapsulation engine, interfacing directly with the DP83848 PHY (MII/RMII), DS2155 (T1/E1), and DS3170 (T3/E3) via dedicated address-mapped chip selects (CS_X1–CS_X3). It provides dual-mode operation: software-driven configuration via ChipView or hardware-switched mode with jumper-selectable T1/E1/T3/E3 line rates and HDLC/PPP framing.

On-board clocking includes 100MHz system oscillator (YB03), configurable RefClk routing (JP24), and independent MCLK sources for DS2155 (YB04) and DS3170 (TP05/T3E3_OSC testpoints), supporting synchronous and asynchronous serial timing domains. All DS33Z11 interface pins-including RMII/MII, serial data, clock, and control signals-are brought out to headers or testpoints for external instrumentation or integration.

FAQ

What is the primary function of the DS33Z11+UNUSED demo kit?

The DS33Z11+UNUSED demo kit is a fully assembled evaluation platform for the DS33Z11 Ethernet transport-over-serial link device. It enables engineers to validate DS33Z11 functionality-including HDLC/PPP framing, T1/E1/T3/E3 line rate support, and Ethernet-to-TDM bridging-using integrated hardware (DP83848 PHY, DS2155, DS3170) and ChipView software for real-time register access and configuration.

Does DS33Z11+UNUSED include the DS33Z11 IC itself?

Yes, the DS33Z11+UNUSED demo kit contains the DS33Z11 IC mounted on the main board, along with companion devices including the DP83848 Ethernet PHY, DS2155 T1/E1 transceiver, and DS3170 T3/E3 transceiver. All are interconnected and accessible via headers, jumpers, and testpoints for comprehensive evaluation of the DS33Z11's transport capabilities.

How is the DS33Z11+UNUSED configured for different line rates (T1/E1 vs. T3/E3)?

DS33Z11+UNUSED supports T1/E1 and T3/E3 modes via hardware jumpers (JP20–JP23) and software configuration. Jumper settings select the active transceiver (DS2155 or DS3170), while ChipView or the on-board device driver loads appropriate .MFG and .INI files (e.g., e1_gapclk_crc4_hdb3_nocas.ini for E1, 70_t3_sct_needscoaxlb.mfg for T3) to configure framing, clocking, and scrambling per ITU-T G.703/G.704 standards.

Can DS33Z11+UNUSED operate without a host PC?

No-DS33Z11+UNUSED requires a Windows-based host PC for operation. ChipView software (provided on CD and downloadable) is mandatory for register-level control, configuration file loading, and status monitoring. The kit connects via RS232 (57.6K, 8N1) or USB, and no standalone or autonomous operation mode is supported.

What documentation and software ship with DS33Z11+UNUSED?

DS33Z11+UNUSED ships with a CD-ROM containing ChipView software, DS33Z11DK data sheet, DS33Z11 data sheet, configuration files (.def, .mfg, .ini), and user manual. All files are also available for download from maxim-ic.com/DS33Z11DK. The manual includes quick setup guides for T1/E1/T3/E3, LED status decoding, jumper maps, and address space layout (e.g., DS33Z11 at 0x1000–0x1FFF).
