Product details
Overview
PSMUX136ZUAEX from Diodes Incorporated is a high-speed differential 2:1 multiplexer/demultiplexer switch with 5.5GHz bandwidth on the A port and 5.3GHz on the B port, 4.6Ω typical RON (A), 5.7Ω typical RON (B), and -37dB crosstalk at 240MHz. It supports 1.8V–5.5V supply, 0V–3.6V analog input range, and operates from -40°C to +125°C - deployed in smartphone high-speed interface routing.
For engineers reviewing the PSMUX136ZUAEX datasheet, PSMUX136ZUAEX pinout, PSMUX136ZUAEX application, or PSMUX136ZUAEX equivalent, key selection criteria include differential signal integrity at >5GHz, sub-100ps propagation delay, power-off leakage protection, and UQFN-10 (1.5×2mm) footprint compatibility with space-constrained mobile PCBs.
Technical Context
The PSMUX136ZUAEX implements a fully differential, bidirectional SPDT switch architecture with independent A1/A2 and B1/B2 differential paths routed to shared COM1/COM2 ports. Its control logic uses dual active-low EN and SEL pins to select between A-port or B-port routing while maintaining Hi-Z state during disable.
It features matched RON flatness (≤1Ω), low capacitance switching (1.5pF CON), and integrated power-off protection that limits leakage current to ±10µA when VDD = 0V - enabling safe hot-swap and battery-backed system operation without signal corruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (-3dB) | 5.5GHz (A port), 5.3GHz (B port): preserves eye diagram integrity for USB 3.2 Gen 2, MIPI D-PHY v2.5, and LPDDR4x data lanes. |
| RON (Typical) | 4.6Ω (A port), 5.7Ω (B port): minimizes insertion loss and voltage drop across high-speed differential signals at 3.3V operation. |
| Propagation Delay | 0.1ns typical: ensures timing alignment critical for parallel differential bus switching without skew-induced jitter. |
| Crosstalk | -37dB @ 240MHz: prevents coupling between active and inactive differential pairs in dense RF/baseband layouts. |
| Supply Voltage Range | 1.8V to 5.5V: enables direct integration with 1.8V, 3.3V, and 5V logic domains without level-shifting circuitry. |
| Operating Temperature | -40°C to +125°C: qualified for automotive infotainment and industrial edge computing environments with thermal cycling stress. |
| Power-Off Leakage | ±10µA max @ VDD = 0V: eliminates current path from live I/O pins to floating supply rail during standby or battery disconnect. |
Pinout & Package
PSMUX136ZUAEX is housed in a 10-pin UQFN package (ZUA code), measuring 1.5mm × 2.0mm with 0.6mm pitch and 0.5mm height. The exposed pad enhances thermal dissipation and must be soldered to PCB ground for optimal EMI performance and junction temperature control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Differential I/O Channel A | Primary high-speed differential pair input/output; routed to COM when SEL = L and EN = L. |
| B1, B2 | Differential I/O Channel B | Secondary high-speed differential pair input/output; routed to COM when SEL = H and EN = L. |
| COM1, COM2 | Common Differential Port | Shared bidirectional I/O node connecting to either A or B channel based on SEL state. |
| SEL | Mode Select Input | Active-high logic control: SEL = H selects B-port path; SEL = L selects A-port path. |
| EN | Enable Input | Active-low chip enable: EN = H forces all switches into Hi-Z state regardless of SEL value. |
| VDD | Positive Supply | Single supply rail powering internal logic and switch bias; supports 1.8V–5.5V operation. |
| GND | Ground Reference | Return path for VDD, analog signals, and digital control; connects to thermal pad for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Bi-Directional 2:1 Mux/DeMux | Enables full-duplex signal routing between two differential sources and one common bus without polarity inversion or DC blocking. |
| Low Propagation Delay (0.1ns) | Maintains phase coherence across multi-lane interfaces like MIPI CSI-2, reducing inter-pair skew and improving receiver eye margin. |
| Power-Off Protection | Prevents back-driving and leakage current flow when VDD is unpowered - essential for hot-plug and battery-powered subsystems. |
| 1.8V Logic-Compatible Control Pins | Accepts 1.8V CMOS logic levels on SEL/EN even when VDD = 5.5V, simplifying interface with low-voltage microcontrollers. |
| Lead-Free & Halogen-Free UQFN | Meets RoHS 3, AEC-Q200 readiness, and automotive PPAP requirements with <900ppm Br/Cl and <1000ppm Sb compounds. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential 2:1 mux applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUXHS4212RTER | Higher RON (6.5Ω typ), lower bandwidth (4.5GHz), no power-off protection, 12-pin WQFN. | Targeted at cost-sensitive consumer notebooks; lacks automotive temp range and leakage control. | Select if board space allows larger package and system does not require zero-leakage during VDD removal. |
| ADG1212YRUZ | Single-ended only, 12-bit precision, 120Ω RON, 100MHz bandwidth, SOIC-16 package. | Designed for precision analog multiplexing, not high-speed digital interfaces. | Only suitable for low-frequency analog signal routing - not a functional substitute for PSMUX136ZUAEX's differential GHz-class operation. |
Compared with TMUXHS4212RTER and ADG1212YRUZ, PSMUX136ZUAEX uniquely delivers differential GHz bandwidth, sub-6Ω RON, and power-off leakage suppression in a 1.5×2mm UQFN - making it the sole fit for space-constrained, thermally demanding, high-data-rate mobile and automotive applications.

FAQ
What is the maximum signal voltage swing supported by PSMUX136ZUAEX?
The device supports analog input/output voltages from -0.3V to +5.5V on COM, A, and B ports, and up to +6V on control pins (SEL/EN). This accommodates standard LVDS (±350mV), MIPI D-PHY (0–1.2V), and USB 3.x (0–1.3V) signal swings without clamping or distortion.
Does PSMUX136ZUAEX require external termination resistors?
No external termination is required for standard 50Ω differential systems. The switch's 1.5pF ON-capacitance and matched RON ensure minimal impedance discontinuity. However, series 22–33Ω resistors may be added near source drivers to dampen reflections in ultra-long (>10cm) trace configurations.
Can EN and SEL be driven directly from a 1.8V GPIO without level shifting?
Yes. The control pins accept VIH ≥ 1.3V and VIL ≤ 0.6V over the full 1.8V–5.5V VDD range, making them compatible with 1.8V CMOS logic outputs without additional translation circuitry - verified per DS44036 Rev 5-2 DC Electrical Characteristics table.
Is the thermal pad on the ZUA package electrically connected internally?
No - the exposed thermal pad is not internally connected to any die node. It must be externally soldered to a PCB ground plane to provide mechanical stability, thermal conduction, and EMI shielding. Floating or unconnected pads degrade thermal performance and increase radiated emissions above 1GHz.
