Analog Devices Inc./Maxim Integrated MAX9213EUM+D

Overview

MAX9213EUM+D from Maxim Integrated is a programmable DC-balanced 21-bit parallel-to-LVDS serializer IC used in high-speed video and imaging data transmission systems. It converts 21 LVTTL/LVCMOS inputs into three LVDS data streams plus one LVDS clock output, supports 16–66MHz parallel clock rates in DC-balanced mode, delivers up to 594Mbps per channel, and operates from a +3.3V supply across –40°C to +85°C - enabling robust automotive display links.

For engineers reviewing the MAX9213EUM+D datasheet, MAX9213EUM+D pinout, MAX9213EUM+D application, or MAX9213EUM+D equivalent, this page provides verified functional specifications, validated TSSOP-48 pin mapping, confirmed AC-coupling capability with ground-shift tolerance, exact DC-balance behavior at 66MHz, and direct compatibility context with DS90CR215/DS90CR217 in non-DC-balanced mode.

Technical Context

The MAX9213EUM+D implements a PLL-based clock multiplication architecture (7× or 9×) to generate LVDS serial timing from a parallel input clock. Its DC-balance logic appends two control bits per 7-bit word to constrain digital sum variation (DSV) to ≤10 on data channels and ≤5 on clock, enabling reliable AC-coupled operation over CAT-5 cable up to 10m.

In non-DC-balanced mode, it serializes 7 bits/cycle at 20–85MHz; in DC-balanced mode, it serializes 9 bits/cycle (7 data + 2 DSV bits) at 16–66MHz. The DCB/NC pin is internally pulled up to VCC, fixing default DC-balanced operation - distinct from MAX9215 (pulled down) and MAX9209/MAX9211 (dual-mode configurable).

Key Specifications

Pinout & Package

MAX9213EUM+D uses a 48-pin Thin Shrink Small Outline Package (TSSOP) with 0.5mm pitch, no exposed thermal pad, and standard JEDEC MO-153 compliance. Pin numbering follows counter-clockwise convention from notch-marked corner.

FAQ

What is the default DC-balance configuration of the MAX9213EUM+D?

The MAX9213EUM+D has the DCB/NC pin internally pulled up to VCC, fixing its default operating mode to DC-balanced. This enables immediate AC-coupling capability without external biasing - unlike MAX9215EUM+ (pulled down, non-DC-balanced default) or MAX9209EUM (configurable). Confirmed in Table 1 of the official datasheet.

Does the MAX9213EUM+D support pin-compatible replacement of DS90CR215MTD?

Yes, the MAX9213EUM+D is pin-compatible with DS90CR215MTD in non-DC-balanced mode, sharing identical TSSOP-48 footprint and signal assignments. However, DCB/NC must be driven low to match DS90CR215 behavior - MAX9213EUM+D's internal pull-up requires explicit override for true drop-in use.

What is the maximum parallel clock frequency supported by the MAX9213EUM+D in DC-balanced mode?

The MAX9213EUM+D supports a maximum parallel clock frequency of 66MHz in DC-balanced mode, yielding a serial data rate of 594Mbps (66MHz × 9 bits). This is validated in the "Detailed Description" section and Figure TOC04 (supply current vs. frequency), confirming stable operation at 66MHz with worst-case pattern loading.

How does the MAX9213EUM+D handle power-down sequencing?

Driving PWRDWN low on the MAX9213EUM+D stops the PLL, disables integrated LVDS termination resistors, places all LVDS outputs in high-impedance state, and reduces supply current to ≤50µA. The device retains configuration but requires full PLL lock time (up to 492µs at 66MHz) before valid LVDS output resumes after PWRDWN release.

What package type does the MAX9213EUM+D use, and does it include an exposed thermal pad?

The MAX9213EUM+D uses a 48-pin Thin Shrink Small Outline Package (TSSOP) with 0.5mm pitch and no exposed thermal pad. This distinguishes it from MAX9213ETM+ (48-pin thin QFN-EP), which includes an exposed paddle for enhanced thermal dissipation - confirmed in the Ordering Information table and Pin Configurations section.
