Product details
Overview
The MAX7375AXR405+T from Maxim Integrated is a factory-trimmed 4.00MHz silicon oscillator in SC70-3 package, designed as a drop-in replacement for ceramic resonators and crystal oscillators in microcontroller and UART clocking applications operating from 2.7V to 5.5V. It delivers rail-to-rail 50% duty cycle square-wave output with ±2% initial accuracy, ±50ppm/°C temp drift, 5ns rise time, and 160psP-P jitter at 8MHz (scaled), enabling robust timing in white goods and industrial controls.
For engineers reviewing the MAX7375AXR405+T datasheet, MAX7375AXR405+T pinout, MAX7375AXR405+T application, or MAX7375AXR405+T equivalent, key selection criteria include its vibration-immune silicon architecture, no-external-component operation, fast 5µs startup, SC70-3 footprint compatibility, and guaranteed -40°C to +125°C performance without load capacitance or biasing networks.
Technical Context
The MAX7375AXR405+T uses a fully integrated BiCMOS oscillator core that generates frequency directly-without PLL-ensuring deterministic startup and stable output across supply (2.7V–5.5V) and temperature (-40°C to +125°C). Its push-pull CMOS output drives 1kΩ to GND or 500Ω to V+, eliminating impedance-matching concerns.
Unlike quartz-based solutions, it avoids high-impedance nodes and mechanical resonance, delivering low EMI susceptibility and immunity to shock, humidity, and board-level vibration-critical for appliance and portable equipment environments where reliability under stress is mandatory.

FAQ
What is the exact output frequency and tolerance of the MAX7375AXR405+T?
The MAX7375AXR405+T is factory-trimmed to 4.00MHz with ±2% initial accuracy at +25°C and V+ = 3.0V. Over the full operating temperature range (-40°C to +125°C) and supply voltage (2.7V to 5.5V), total frequency deviation remains within ±4% due to ±50ppm/°C temperature coefficient and supply sensitivity. This specification is guaranteed by design and characterization-not production tested per unit-but validated across process corners and environmental extremes.
Does the MAX7375AXR405+T require external load capacitors or biasing components?
No, the MAX7375AXR405+T requires no external components. Its fully integrated oscillator eliminates the need for load capacitors, feedback resistors, or crystal-matching networks. When retrofitting a crystal-based design, all external timing components must be removed from the µC clock input pins. The device's push-pull CMOS output drives the microcontroller clock input directly-no series termination or level-shifting is necessary.
What is the startup time of the MAX7375AXR405+T, and how should system reset be coordinated?
The MAX7375AXR405+T achieves stable output within 5µs after V+ rises above 2.7V. To ensure reliable microcontroller boot, a reset circuit must hold the µC in reset until at least 5µs after V+ exceeds 2.7V-not after power-on or after V+ reaches nominal voltage. This timing aligns with the oscillator's internal stabilization, preventing clock-related boot failures in safety-critical applications like appliance control.
Can the MAX7375AXR405+T operate beyond its specified -40°C to +125°C range?
The MAX7375AXR405+T was characterized to function normally up to +135°C, but production testing and qualification are strictly limited to -40°C to +125°C. Operation outside this range is not guaranteed, and reliability data (e.g., MTBF, parametric shift) is unavailable. For extended temperature use, contact Maxim Integrated (now Analog Devices) directly to discuss feasibility, qualification requirements, and custom screening options.
How does the MAX7375AXR405+T compare to quartz crystals in terms of EMI and vibration resistance?
The MAX7375AXR405+T exhibits superior EMI and vibration resistance compared to quartz crystals because it lacks piezoelectric mechanical resonance and high-impedance nodes. Its solid-state BiCMOS oscillator is immune to board flexure, motor-induced shock, and electromagnetic interference-unlike quartz devices, which can suffer frequency pulling, spurious modes, or complete stoppage under mechanical stress. This makes the MAX7375AXR405+T especially suited for washing machines, power tools, and portable equipment.
