Product details
Overview
MAX9210EUM+TD from Maxim Integrated is a 21-bit LVDS deserializer IC that converts three LVDS serial data streams and one parallel-rate LVDS clock into 21 single-ended LVCMOS/LVTTL outputs with programmable DC balance, 8–34MHz operation in DC-balanced mode, and 1.8V–5V configurable output logic levels. It serves as the receiver in high-speed point-to-point video/data links for digital copiers and laser printers.
For engineers reviewing the MAX9210EUM+TD datasheet, MAX9210EUM+TD pinout, MAX9210EUM+TD application, or MAX9210EUM+TD equivalent, key selection criteria include rising-edge output strobe timing, AC-coupling support via DC-balance programming, IEC 61000-4-2 Level 4 ESD tolerance (±15kV air), low-frequency EMI reduction, and compatibility with MAX9209/MAX9213 serializers.
Technical Context
The MAX9210EUM+TD implements a PLL-based deserialization architecture synchronized to an incoming parallel-rate LVDS clock (RxCLK IN±), supporting both DC-balanced (7 data + 2 control bits/cycle) and non-DC-balanced (7 bits/cycle) modes controlled by the DCB/NC pin. Its internal bias network enables AC-coupled link operation across wide common-mode voltage ranges.
It features fail-safe LVDS inputs in non-DC-balanced mode, high-impedance outputs during power-down (PWRDWN low), and separate VCC (3.3V digital core) and VCCO (1.8V–5V output supply) domains. The device uses a 48-pin TSSOP package with dedicated LVDS GND, PLL GND, and analog/digital ground separation to maintain signal integrity at up to 1.785Gbps aggregate throughput.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Deserialization Width | 21 single-ended LVCMOS/LVTTL outputs - supports full parallel interface to FPGA or ASIC video processors |
| Input Interface | Three LVDS data pairs (RxIN0±, RxIN1±, RxIN2±) + one LVDS clock pair (RxCLK IN±) - compliant with ANSI TIA/EIA-644 standard |
| DC Balance Control | Programmable via DCB/NC pin - enables AC-coupling isolation and extends input common-mode range beyond ±1V |
| Operating Frequency | 8–34MHz parallel clock in DC-balanced mode; 10–40MHz in non-DC-balanced mode - optimized for low-EMI printing engine timing |
| Output Supply Range | VCCO = 1.8V to 5.0V - allows direct interfacing to 1.8V, 2.5V, 3.3V, or 5V logic without level shifters |
| ESD Protection | ±15kV air / ±8kV contact (IEC 61000-4-2) on LVDS inputs - meets industrial printer environmental robustness requirements |
| Power-Down Current | <50µA - enables dynamic power gating in multi-deserializer bused architectures |
Pinout & Package
MAX9210EUM+TD is housed in a 48-lead, 0.25mm pitch, low-profile TSSOP package (JEDEC MO-153) with exposed thermal pad (not electrically connected). Pin functions are validated per Maxim's official datasheet Rev 6 (19-2864).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,4,5,45–47 | RxOUT14–RxOUT20 | Channel 2 single-ended data outputs - routed separately to minimize crosstalk in high-density PCB layouts |
| 3,25,32,38,44 | GND | Digital ground reference - multiple pins reduce ground bounce in 21-bit parallel output switching |
| 6 | DCB/NC | DC-balance mode select - high/float = DC-balanced; low = non-DC-balanced; not 5V tolerant |
| 7,13,18 | LVDS GND | Dedicated LVDS receiver ground - isolated from digital GND to suppress coupling noise into sensitive differential inputs |
| 8,9,10,11,14,15,16,17 | RxIN0±, RxIN1±, RxIN2±, RxCLK IN± | Four LVDS differential input pairs - internally terminated with 100Ω-equivalent differential impedance |
| 12 | LVDS VCC | LVDS receiver supply - decoupled separately to ensure clean bias for high-speed analog front-end |
| 19,21 | PLL GND | PLL ground reference - critical for jitter performance; must be tied to quiet ground plane |
| 20 | PLL VCC | PLL supply - requires tight decoupling (0.1µF + 0.001µF) to minimize phase noise |
| 22 | PWRDWN | 5V-tolerant power-down control - drives all outputs to high-Z when low; internally pulled down |
| 23 | RxCLK OUT | Rising-edge parallel clock output - synchronous to deserialized data; used for latch timing in downstream logic |
| 24,26,27,29,30,31,33 | RxOUT0–RxOUT6 | Channel 0 single-ended outputs - grouped for localized routing to first 7-bit data bus segment |
| 28,36,48 | VCCO | Output supply voltage - independent of core VCC; sets VOH/VOL thresholds for interfacing logic |
| 34,35,37,39,40,41,43 | RxOUT7–RxOUT13 | Channel 1 single-ended outputs - physically separated from Channel 0 to reduce inter-channel skew |
| 42 | VCC | +3.3V digital core supply - powers internal logic, PLL, and control circuitry; not 5V tolerant |
Key Features
| Feature | Design Value |
|---|---|
| Rising-edge output strobe | Enables synchronous latching in legacy 21-bit parallel interfaces designed for DS90CR216A/DS90CR218A timing |
| Programmable DC balance | Allows AC-coupling with external capacitors - eliminates ground potential mismatch errors in long cable runs |
| Slower output transitions (low-frequency version) | Reduces broadband EMI emissions by extending rise/fall times - critical for FCC/CE compliance in office equipment |
| High-impedance outputs on PWRDWN | Permits busing two MAX9210EUM+TD outputs onto a shared 21-bit bus - simplifies multiplexer design without external switches |
| Fail-safe LVDS inputs (non-DC-balanced mode) | Drives all outputs low if any LVDS input is open, shorted, or undriven - prevents undefined states during cable disconnect |
| PLL requires no external components | Eliminates loop filter tuning and external capacitor placement - reduces BOM count and layout complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 21-bit LVDS deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90CR216A | No DC-balance programming; fixed non-DC-balanced operation only; no AC-coupling support; lower max frequency (66MHz vs 85MHz in non-DC mode) | Requires DC-coupled links; unsuitable for ground-shifted or long-cable applications where common-mode drift exceeds ±1V | Select DS90CR216A only for cost-sensitive, short-trace, fixed-frequency designs where AC-coupling is unnecessary |
| MAX9220EUM+ | Falling-edge output strobe; identical DC-balance functionality and frequency range; same pinout but incompatible strobe edge timing | Cannot replace MAX9210EUM+TD in systems relying on rising-edge clock sampling without redesigning downstream latch timing | Choose MAX9220EUM+ only when falling-edge strobe aligns with existing FPGA/ASIC capture logic or when migrating from legacy falling-edge designs |
Compared with DS90CR216A and MAX9220EUM+, the MAX9210EUM+TD uniquely combines rising-edge strobe timing, programmable DC balance for AC-coupling, and low-EMI output transitions - making it optimal for new digital copier and laser printer platforms requiring robust, flexible, and EMI-compliant video data reception.

FAQ
What is the function of the DCB/NC pin on the MAX9210EUM+TD?
The DCB/NC pin on the MAX9210EUM+TD selects DC-balanced or non-DC-balanced deserialization mode: high or floating enables DC-balanced operation (supporting AC-coupling and wider common-mode range), while low forces non-DC-balanced mode (compatible with legacy devices like DS90CR216A). It is not 5V tolerant and must be driven between GND and VCC.
Does the MAX9210EUM+TD support AC-coupled LVDS inputs?
Yes, the MAX9210EUM+TD supports AC-coupled LVDS inputs when configured in DC-balanced mode via the DCB/NC pin. Its internal bias network (42kΩ to +1.2V) maintains proper common-mode voltage, enabling reliable operation across ground-potential differences up to the coupling capacitor's voltage rating minus half the differential swing.
What is the maximum data throughput of the MAX9210EUM+TD?
The MAX9210EUM+TD achieves up to 1.785Gbps aggregate throughput: in non-DC-balanced mode at 85MHz × 7 bits = 595Mbps per channel × 3 channels = 1.785Gbps; in DC-balanced mode at 34MHz × 9 bits = 306Mbps per channel × 3 channels = 918Mbps. Throughput depends on selected mode and clock frequency.
Can the MAX9210EUM+TD be used with a 1.8V output supply?
Yes, the MAX9210EUM+TD supports VCCO = 1.8V, enabling direct interface to 1.8V FPGA or ASIC I/O banks. At 1.8V, its VOH is ≥1.7V and VOL is ≤0.1V under 100µA load, meeting LVCMOS18 specifications. Output drive strength scales with VCCO, so timing margins must be verified at 1.8V.
How does the PWRDWN pin affect output behavior in the MAX9210EUM+TD?
Driving PWRDWN low places all 21 RxOUT_ outputs and RxCLK OUT into high-impedance state, stops the PLL, and reduces supply current to ≤50µA. This enables safe busing of multiple MAX9210EUM+TD outputs. A 100ns delay is required between disabling one device and enabling another to prevent bus contention.
