Product details
Overview
DS33ZH11+ from Maxim Integrated is a 10/100 Ethernet-to-TDM mapper IC that encapsulates IEEE 802.3 MAC frames into HDLC or X.86 (LAPS) for transport over synchronous PDH/TDM links up to 52Mbps. It supports MII/RMII Ethernet interfaces, features a programmable CIR controller with 512kbps granularity, and operates at 1.8V core with 3.3V-tolerant I/O-used in LAN extension over T1/E1, DSL, and SONET tributaries.
For engineers reviewing the DS33ZH11+ datasheet, DS33ZH11+ pinout, DS33ZH11+ application, or DS33ZH11+ equivalent, this device serves as a hardware/SPI-mode-only Ethernet mapper with fixed 100-ball CSBGA packaging, no external microprocessor dependency, and deterministic bandwidth allocation for carrier-grade transparent LAN services.
Technical Context
The DS33ZH11+ implements store-and-forward packet processing with full wire-speed throughput on both Ethernet and serial TDM paths. Its dual-clock domain architecture separates Ethernet (MII/RMII) timing from synchronous serial interface timing, enabling independent transmit/receive clocking for T1/E1/J1, T3/E3, OC-1, or V.35/Optical physical layers.
It integrates an HDLC/X.86 mapper with configurable FCS generation and interframe fill, a BERT engine for serial link diagnostics, and JTAG-compliant IEEE 1149.1 test infrastructure. The device boots autonomously via SPI EEPROM or hardware strapping-no host processor required.

Pinout & Package
DS33ZH11+ is housed in a 100-ball, 10mm × 10mm CSP-BGA (CSBGA) package, pin-compatible with Maxim's DS33ZH11 family. Pin assignments are optimized for hardware/SPI mode operation only-no parallel microprocessor interface pins are functional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDCORE | Core Power Supply | 1.8V supply input for internal logic and serializer/deserializer blocks; requires local 100nF decoupling. |

| REFCLK | Reference Clock Input | 25MHz or 50MHz clock source for Ethernet MAC timing; drives internal PLL for MII/RMII clock generation. |
| TXCLK | TDM Transmit Clock Output | Programmable synchronous clock output (up to 52MHz) aligned to outgoing HDLC/X.86 frame boundaries. |
| RXCLK | TDM Receive Clock Input | External synchronous clock input for recovering incoming TDM data-supports independent TX/RX clock domains. |
| MOSI/MISO/SCLK/SS | SPI Interface | Master-only SPI bus for configuration EEPROM access; enables boot-time register initialization without host CPU. |
| MDIO/MDC | PHY Management Interface | IEEE 802.3 MDIO/MDC interface for reading/writing PHY registers-required when connecting to external 10/100 PHY. |
| RESET_N | Active-Low Reset Input | Asynchronous reset signal-asserted low for ≥100ns initiates full device initialization and register clearing. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware/SPI Mode Only | Eliminates need for external microcontroller-configuration loaded directly from SPI EEPROM at power-up for autonomous operation. |
| HDLC/X.86 Encapsulation | Enables standards-compliant framing for carrier-grade Ethernet over legacy TDM infrastructure (T1/E1, OC-1, G.SHDSL). |
| CIR Bandwidth Controller | Provides deterministic, sub-Mbps bandwidth slicing-critical for SLA-governed multi-tenant LAN extension services. |
| Built-in BERT Engine | Supports PRBS pattern generation and monitoring on serial TDM interface-enables field-deployable link integrity validation without test equipment. |
| 1.8V Core + 3.3V I/O | Reduces active power by ~40% vs. 3.3V-core alternatives while maintaining interoperability with common PHYs and control logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet-to-TDM mapping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS33Z11+ | 169-ball CSBGA; supports parallel microprocessor interface and full MII/RMII + hardware mode; higher pin count, larger footprint. | Used where host CPU control, flexible configuration, or external SDRAM buffering is required. | Select DS33Z11+ when system design includes external microcontroller or requires runtime register reconfiguration. |
| MAX24287 | Dual-port T1/E1 framer with integrated Ethernet MAC; no HDLC/X.86 mapper; supports only T1/E1 physical layer, not 52Mbps wideband. | Targeted at narrowband T1/E1 channelized voice/data aggregation-not transparent LAN extension. | Choose MAX24287 only for legacy TDM circuit emulation, not for Ethernet frame tunneling over broadband TDM. |
Compared with DS33Z11+, DS33ZH11+ trades microprocessor interface flexibility for smaller size and lower BOM cost-ideal for space-constrained, firmware-less deployments. Unlike MAX24287, it delivers true Ethernet transparency via HDLC/X.86, supporting full 52Mbps line-rate transport across diverse PDH/SONET/DSL physical layers.

FAQ
What is the primary function of the DS33ZH11+?
The DS33ZH11+ is a dedicated Ethernet-to-TDM mapper IC that encapsulates IEEE 802.3 MAC frames into HDLC or X.86 (LAPS) format for transport over synchronous PDH/TDM links. Unlike general-purpose processors or FPGAs, the DS33ZH11+ performs this mapping in hardware with deterministic latency, supporting up to 52Mbps line-rate throughput without external software intervention. Its fixed-function architecture ensures consistent performance in carrier-grade LAN extension systems.
Does the DS33ZH11+ require an external microprocessor to operate?
No, the DS33ZH11+ does not require an external microprocessor. It supports autonomous hardware/SPI mode operation: configuration is loaded from an external SPI EEPROM at power-up, and all packet processing-including HDLC/X.86 framing, CIR bandwidth control, and BERT diagnostics-is handled internally. This eliminates firmware development, reduces BOM count, and improves system reliability compared to host-dependent alternatives like the DS33Z11+.
What serial interfaces does the DS33ZH11+ support for TDM connectivity?
The DS33ZH11+ supports bidirectional synchronous TDM serial links up to 52Mbps, compatible with T1/E1/J1, T3/E3, V.35/Optical, OC-1/EC-1, and SONET/SDH tributary physical layers. It provides independent TXCLK and RXCLK signals to accommodate separate transmit and receive clock domains-essential for phase-sensitive applications such as G.SHDSL backhaul and SONET tributary mapping where clock recovery stability directly impacts bit error rate.
How does the Committed Information Rate (CIR) controller in the DS33ZH11+ work?
The DS33ZH11+ CIR controller allocates fractional bandwidth in precise 512kbps increments up to the full line rate, enabling granular QoS enforcement for multi-tenant Ethernet services. It operates in the WAN transmit path to shape outgoing traffic before HDLC/X.86 encapsulation-ensuring SLA compliance without packet drops or jitter. This hardware-implemented CIR differs from software-based traffic shapers by guaranteeing deterministic latency and eliminating CPU overhead, making it ideal for carrier-class transparent LAN services.
Is the DS33ZH11+ pin-compatible with the DS33Z11+?
No, the DS33ZH11+ is not pin-compatible with the DS33Z11+. The DS33ZH11+ uses a 100-ball CSBGA package optimized for hardware/SPI mode only, while the DS33Z11+ uses a 169-ball CSBGA with full parallel microprocessor interface support. Their pinouts differ significantly-especially in address/data bus, interrupt, and control signal assignments. Board designs must be re-laid out to migrate between these variants; they are functionally related but physically incompatible.
