Product details
Overview
The MAX13171EETU+ from Maxim Integrated is a multiprotocol, pin-selectable DTE/DCE interface transceiver supporting V.28 (RS-232), V.10 (RS-423), V.11 (RS-449/V.36/RS-530/RS-530A/X.21), and V.35 protocols. It delivers high-speed clock and data signal transmission with 20/40Mbps max data rate in V.11/V.35 modes, true fail-safe receivers, and integrated charge-pump operation from a single +3.135V to +5.5V supply. It is used in telecom CSU/DSU units and data routers requiring protocol-flexible physical layer interfacing.
For engineers reviewing the MAX13171EETU+ datasheet, MAX13171EETU+ pinout, MAX13171EETU+ application, or MAX13171EETU+ equivalent, this page provides verified electrical specifications, pin-level circuit roles, protocol-specific performance metrics (V.11 differential output voltage, V.35 loaded differential voltage, no-cable mode current), thermal shutdown behavior, and ESD protection ratings per IEC 61000-4-2.
Technical Context
The MAX13171EETU+ implements dual-mode transmitter/receiver channels optimized for both V.11 (balanced, ±5V differential) and V.35 (±0.55V differential, 100Ω termination) signaling, with independent logic-level translation via VL input (1.62V–5.5V). Its internal charge pump generates ±5.5V rails from a single supply, enabling compliant RS-449 and V.35 operation without external DC-DC converters.
Pin-selectable configuration (via M0/M1/M2 and DCE/DTE inputs) determines protocol mapping, termination mode, and signal polarity. Fail-safe receiver design ensures valid logic outputs under open-circuit or shorted-line conditions while maintaining strict V.11 common-mode range (–7V to +7V) and V.35 differential threshold (–200mV to –50mV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | +3.135V to +5.5V - enables direct connection to standard 3.3V or 5V system rails without level-shifting. |
| Max Data Rate | 40Mbps in V.11/V.35 modes - supports high-speed synchronous serial links in telecom backhaul and router interfaces. |
| V.11 Differential Output | ±5.26V (loaded, 50Ω) - meets RS-449/RS-530 full-swing compliance with <0.2V magnitude variation over temperature. |
| V.35 Loaded Differential Voltage | ±0.55V (full load, –4V < VCM < +4V) - satisfies ITU-T V.35 specification for balanced digital interface timing. |
| No-Cable Mode Current | <10µA - reduces standby power in idle link states, critical for energy-constrained network edge devices. |
| ESD Protection | ±15kV HBM, ±12kV IEC 61000-4-2 air-gap - protects against field-induced transients on exposed telecom line pins. |
| Operating Temp | –40°C to +85°C - qualified for industrial and telecom equipment deployed in uncontrolled environments. |
Pinout & Package
Package: 38-pin TQFN-EP (5mm × 7mm, exposed pad), RoHS-compliant, thermally enhanced for sustained high-speed operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1, T2, T3 | V.11 Transmitter Outputs | Differential pairs driving RS-449/RS-530 lines; support 40Mbps with <3ns channel skew. |
| R1, R2, R3 | V.11 Receiver Inputs | Fail-safe inputs with –200mV to –50mV threshold; tolerate –7V to +7V common-mode range. |
| TXD, RXD, TXC, RXC | V.28/V.35 Data/Clock I/O | Configurable as V.28 (±6V swing) or V.35 (±0.55V) based on M0–M2 settings and termination selection. |
| M0, M1, M2, DCE/DTE | Protocol & Polarity Control | Hardware-selectable inputs defining DTE/DCE role, V.10/V.11/V.35 mode, and signal inversion. |
| VCC, VL, GND, EP | Power & Reference | VL sets logic-level reference (1.62V–5.5V); EP improves thermal dissipation in high-current modes. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-SELECTABLE PROTOCOL SUPPORT | Single hardware configuration (M0–M2 + DCE/DTE) selects V.28, V.10, V.11, or V.35 mode - eliminates firmware dependency for physical layer adaptation. |
| INTEGRATED CHARGE PUMP | Generates ±5.5V transmitter rails from +3.3V/+5V supply - removes need for external DC-DC converters in space-constrained telecom modules. |
| TRUE FAIL-SAFE RECEIVERS | Guaranteed logic-high output when inputs are open, shorted, or below –200mV - prevents spurious framing errors in noisy line conditions. |
| FLEXIBLE VL LOGIC REFERENCE | Supports 1.62V–5.5V logic interface - enables direct connection to 1.8V FPGA I/O banks or 3.3V microcontroller UART peripherals. |
| NO-CABLE MODE | Disables all transmitters/receivers into high-Z state with <10µA ICC - simplifies power management during link down events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3322EEUP+ | RS-232-only (V.28), no V.11/V.35 support; lower ESD (±15kV HBM only); 20-pin TSSOP package. | Limited to point-to-point RS-232 links; unsuitable for synchronous telecom protocols requiring V.35 timing or V.11 differential integrity. | Select when only legacy RS-232 connectivity is needed and board space permits larger TSSOP footprint. |
| SN65LVDS32DR | LVDS-only (not multiprotocol); no charge pump; requires external ±3.3V supplies; 8-pin SOIC. | Designed for short-reach, low-voltage differential signaling (e.g., FPGA-to-FPGA), not telecom line driving or fail-safe receiver operation. | Choose for cost-sensitive, low-power embedded links where V.35/V.11 compliance is unnecessary. |
Compared with MAX3322EEUP+ and SN65LVDS32DR, the MAX13171EETU+ uniquely integrates V.28/V.10/V.11/V.35 support, on-chip charge pump, fail-safe receivers, and 38-pin TQFN packaging - making it the only solution for compact, multi-standard telecom interface designs requiring single-supply operation and robust line fault tolerance.

FAQ
What protocols does the MAX13171EETU+ support?
The MAX13171EETU+ supports V.28 (RS-232), V.10 (RS-423), V.11 (RS-449/V.36/RS-530/RS-530A/X.21), and V.35 protocols. Protocol selection is determined by hardware pin configuration (M0, M1, M2, DCE/DTE), and the device maintains full electrical compliance-including differential voltage levels, timing, and termination-for each mode as specified in the official MAX13171EETU+ datasheet.
Does the MAX13171EETU+ require external charge-pump capacitors?
Yes, the MAX13171EETU+ requires external charge-pump capacitors: C1 and C2 = 1µF, and C3, C4, C5 = 4.7µF (per Figure 15 in the MAX13171EETU+ datasheet). These capacitors stabilize the internal ±5.5V charge-pump rails used for V.11 and V.35 transmitter operation; omitting them results in noncompliant output voltage and potential functional failure.
What is the purpose of the VL pin on the MAX13171EETU+?
On the MAX13171EETU+, the VL pin sets the logic-level reference for all digital inputs and outputs, supporting 1.62V to +5.5V. This allows direct interfacing with diverse host logic-such as 1.8V FPGAs or 3.3V microcontrollers-without external level shifters. The MAX13171EETU+'s VOH and VOL are defined relative to VL, ensuring noise margin and timing compatibility across voltage domains.
How does the no-cable mode function on the MAX13171EETU+?
The no-cable mode on the MAX13171EETU+ disables all transmitter and receiver outputs into high-impedance states and reduces supply current to <10µA. It is activated automatically when cable detection logic identifies an open or disconnected line, or manually via control inputs. This feature minimizes power consumption and prevents signal contention during link-down conditions in the MAX13171EETU+'s operational profile.
Is the MAX13171EETU+ pin-compatible with the MAX13173EETU+ or MAX13175EETU+?
No, the MAX13171EETU+, MAX13173EETU+, and MAX13175EETU+ are functionally complementary but not pin-compatible. The MAX13171EETU+ handles high-speed data/clock signals (T1/T2/T3, TXD/RXD), the MAX13173EETU+ manages control signals (CTS/RTS/DTR), and the MAX13175EETU+ provides termination networks. Each has distinct pin assignments and cannot be substituted without PCB redesign. All three share the same 38-pin TQFN-EP package outline but differ electrically and physically in pin function.
