Analog Devices Inc./Maxim Integrated MAX9206EAI

Overview

MAX9206EAI from Maxim Integrated is a 10-bit BLVDS deserializer IC that converts high-speed serial LVDS data streams into parallel LVCMOS/LVTTL outputs with recovered clock and frame lock. It operates at 450Mbps serial input rate, accepts 16MHz–45MHz reference clock, and delivers low-jitter (720ps p-p) performance in automotive-grade -40°C to +85°C temperature range. Used in backplane interconnects and digital cross-connect systems where skew reduction and hot-insertion capability are critical.

For engineers reviewing the MAX9206EAI datasheet, MAX9206EAI pinout, MAX9206EAI application, or MAX9206EAI equivalent, this page provides verified technical context, real-world timing behavior, confirmed package mapping to 28-pin SSOP, validated pin functions including RCLK_R/F edge selection and PWRDN-controlled power-down, and two field-validated alternative parts for unidirectional serializer/deserializer links.

Technical Context

The MAX9206EAI implements a PLL-based clock recovery architecture synchronized to incoming BLVDS serial data, achieving frequency lock, bit lock, and frame lock simultaneously to generate a word-aligned 10-bit parallel output and stable RCLK. Its internal fail-safe circuit drives undriven RI+/RI- inputs high, enabling robust link detection without external biasing.

It supports programmable strobe edge selection (rising/falling) via RCLK_R/F, enables output disable without losing lock via REN, and enters sub-600µA power-down mode when PWRDN is asserted low - all while maintaining full compatibility with MAX9205/MAX9207 serializers and DS92LV1212A/DS92LV1224 pinouts.

Key Specifications

Pinout & Package

MAX9206EAI is housed in a 28-pin SSOP (Shrink Small Outline Package) with 0.635mm pitch, RoHS-compliant, and rated for -40°C to +85°C operation. The package includes separate analog (AGND/AVCC) and digital (DGND/DVCC) supply domains to minimize noise coupling.

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar deserializer applications.

Compared with DS92LV1212A, MAX9206EAI provides superior jitter tolerance (720ps vs. ~500ps) and integrated fail-safe biasing, while MAX9208EAI+ trades lower-frequency robustness for higher bandwidth - making MAX9206EAI optimal for cost-sensitive, mid-speed industrial links requiring guaranteed lock under variable signal conditions.

Availability

MAX9206EAI is available at Aetrix Electronics and suitable for backplane interconnects, digital cross-connect systems, and DSLAM backplane links requiring stable component supply, automotive-grade temperature resilience, and long-term lifecycle support.

Supply support for MAX9206EAI includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum serial data rate supported by the MAX9206EAI?

The MAX9206EAI supports a maximum serial input rate of 450Mbps, derived from its 10-bit parallel interface operating at up to 45MHz reference clock frequency. This rate is confirmed in the Absolute Maximum Ratings and AC Electrical Characteristics sections of the official datasheet, and applies across the full -40°C to +85°C temperature range with proper termination and layout.

Does the MAX9206EAI require an external reference clock to function?

Yes, the MAX9206EAI requires an external 16MHz–45MHz LVCMOS/LVTTL reference clock applied to the REFCLK pin for initial PLL lock and fallback timing. Once locked to the incoming BLVDS serial stream, it tracks the serializer's TCLK, but REFCLK remains necessary for power-up initialization and resynchronization after loss of lock.

How does the MAX9206EAI handle undriven or disconnected serial inputs?

The MAX9206EAI includes an on-chip fail-safe circuit that pulls the RI+/RI- differential inputs high when undriven, ensuring LOCK reflects link status even during cable disconnect. This behavior is documented in the "Input Fail-Safe" section and eliminates the need for external pull-up resistors in most implementations.

Can the MAX9206EAI be used with the MAX9207 serializer?

Yes, the MAX9206EAI is explicitly designed to pair with the MAX9207 serializer, as stated in the General Description and Typical Operating Circuit. Their interoperability includes matching frame structure (12-bit serial words: 10 data + 2 framing bits), compatible voltage levels, and synchronized lock behavior - confirmed across all functional and timing specifications.

What is the purpose of the RCLK_R/F pin on the MAX9206EAI?

The RCLK_R/F pin on the MAX9206EAI selects the clock edge used to strobe the 10-bit ROUT_ outputs: logic high selects the rising edge of RCLK, and logic low selects the falling edge. This feature provides timing flexibility to meet setup/hold requirements of downstream logic, and is validated in the Pin Description and Figure 5 timing diagrams.
