Product details
Overview
MAX7375AXR495-T from Maxim Integrated is a factory-trimmed 3-pin silicon oscillator delivering a precise 4.95MHz rail-to-rail square-wave clock output with ±2% initial accuracy, ±50ppm/°C temperature drift, and 5µs startup time-designed as a direct drop-in replacement for ceramic resonators and crystals in microcontroller and UART clocking applications operating from 2.7V to 5.5V.
For engineers reviewing the MAX7375AXR495-T datasheet, MAX7375AXR495-T pinout, MAX7375AXR495-T application, or MAX7375AXR495-T equivalent, key selection criteria include its SC70-3 package compatibility, vibration/EMI immunity, no-external-component operation, and guaranteed -40°C to +125°C industrial temperature performance.
Technical Context
The MAX7375AXR495-T uses a fully integrated BiCMOS oscillator core without PLL or external timing components, generating a stable 4.95MHz output directly from internal trimming. Its push-pull CMOS output drives 1kΩ to ground or 500Ω to V+ within 300mV of rails, ensuring robust logic-level compatibility with µC clock inputs.
It exhibits low jitter (160psP-P at 8MHz, scaled proportionally), fast 5ns rise/fall times, and minimal supply-voltage sensitivity (<±0.2% frequency shift over 2.7V–5.5V), making it suitable for noise-sensitive embedded systems where crystal-based solutions suffer from EMI or mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 4.95MHz nominal-factory-trimmed, no external load capacitors required. |
| Initial Accuracy | ±2% at +25°C-guaranteed tolerance eliminates need for post-production calibration. |
| Temp Drift | ±50ppm/°C-enables stable timing across automotive and appliance thermal cycles. |
| Startup Time | 5µs-ensures rapid system initialization after power-on, compatible with µC reset timing. |
| Supply Range | 2.7V to 5.5V-supports 3V, 3.3V, and 5V logic domains without level-shifting. |
| Output Drive | ±10mA-sufficient to drive heavy capacitive loads or multiple CMOS inputs directly. |
| Duty Cycle | 40%–60%-ensures balanced high/low periods for reliable µC clock sampling. |
| Jitter (8MHz ref) | 160psP-P-measured over 20s with 500MHz scope; scales linearly with period. |
Pinout & Package
MAX7375AXR495-T is housed in a space-saving 3-pin SC70-3 package (2.0mm × 2.1mm × 0.95mm), optimized for high-density PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive supply input | Accepts 2.7V–5.5V; requires local 0.1µF ceramic decoupling to GND. |
| 2 (CLOCK) | CMOS push-pull clock output | Delivers rail-to-rail 4.95MHz square wave; drives µC clock input directly-no series resistor or termination needed. |
| 3 (GND) | Ground reference | Return path for supply and output current; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| No external components | Eliminates load capacitors, feedback resistors, and bias networks-reduces BOM count and layout complexity. |
| Vibration/EMI immunity | Monolithic silicon design avoids piezoelectric sensitivity-ideal for automotive and white-goods environments. |
| Rail-to-rail 50% duty cycle | Ensures symmetrical timing margins for both rising- and falling-edge-triggered peripherals. |
| Low-output impedance | Push-pull driver prevents signal corruption in humid or contaminated conditions-no high-impedance nodes. |
| Fast 5µs startup | Enables immediate clock availability after power ramp-simplifies power sequencing with µC reset circuits. |
| -40°C to +125°C operation | Qualified across full industrial temperature range-no derating or thermal monitoring required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1533AI-H4-33E-4.950000G | MEMS-based; ±10ppm initial accuracy; 1.62V–3.63V supply; 1.5µs startup. | Lower drift (±1.5ppm/°C) but narrower voltage range-requires separate LDO if system runs at 5V. | Preferred for ultra-low-drift, low-voltage portable designs; not suitable for 5V-only systems. |
| ABM3B-4.950MHZ-D2Y-T | Quartz crystal with built-in oscillator circuit; ±50ppm initial accuracy; 1.8V–3.3V only; 10ms startup. | Higher EMI susceptibility and mechanical fragility; incompatible with 5V or wide-temp industrial use. | Only viable for cost-sensitive 3.3V consumer devices where vibration immunity is non-critical. |
Compared with SiT1533AI-H4-33E-4.950000G and ABM3B-4.950MHZ-D2Y-T, the MAX7375AXR495-T uniquely balances 5V compatibility, industrial temperature range, fast startup, and vibration resilience-making it the optimal choice for ruggedized embedded systems without MEMS or quartz trade-offs.

FAQ
What is the exact output frequency of the MAX7375AXR495-T?
The MAX7375AXR495-T is factory-trimmed to deliver a precise 4.95MHz nominal output frequency. This value is fixed and non-adjustable-no external components or programming are required to set or modify the frequency. The device achieves ±2% initial accuracy at +25°C and maintains stability across its full -40°C to +125°C operating range.
Does the MAX7375AXR495-T require external load capacitors like quartz crystals?
No, the MAX7375AXR495-T does not require external load capacitors or any other timing components. It is a fully integrated silicon oscillator with internal frequency-setting circuitry. Unlike quartz crystals or ceramic resonators, the MAX7375AXR495-T operates as a self-contained clock source-simply connect V+, GND, and route the CLOCK output to the target microcontroller.
Can the MAX7375AXR495-T operate at 5V supply voltage?
Yes, the MAX7375AXR495-T is fully specified for operation from 2.7V to 5.5V, including standard 5V systems. Its rail-to-rail push-pull output remains functional and stable across this entire range, delivering consistent 4.95MHz timing without degradation in accuracy, jitter, or startup time-even at the 5.5V absolute maximum.
Is the MAX7375AXR495-T pin-compatible with other MAX7375 variants?
Yes, all MAX7375 variants-including MAX7375AXR495-T-share identical SC70-3 pinout (V+, CLOCK, GND) and electrical behavior. Only the factory-trimmed frequency differs between part numbers. This allows seamless frequency substitution within the same PCB layout, provided the target application supports the selected frequency.
What is the startup time specification for the MAX7375AXR495-T?
The MAX7375AXR495-T achieves full-frequency output stabilization in 5µs after V+ rises above the minimum operating threshold (~1.65V at +25°C). This fast startup enables immediate µC clock availability-critical for systems requiring rapid wake-up or deterministic power-on timing without waiting for crystal ring-down or PLL lock.
