Product details
Overview
DF3067RX20V from Maxim Integrated is a factory-trimmed 3-pin silicon oscillator delivering a precise 12MHz rail-to-rail square-wave clock output with ±2% initial accuracy, 5µs startup time, and ±100ppm/°C temperature drift-designed as a robust, vibration- and EMI-resistant replacement for ceramic resonators and crystal oscillators in microcontroller and UART clocking applications operating from 2.7V to 5.5V.
For engineers reviewing the DF3067RX20V datasheet, DF3067RX20V pinout, DF3067RX20V application, or DF3067RX20V equivalent, this device offers plug-in compatibility with standard SC70-3 footprints, no external load capacitors, fast startup under wide temperature (-40°C to +125°C), and low jitter (180psP-P at 16MHz) - critical for timing-sensitive embedded control and automotive systems.
Technical Context
The DF3067RX20V implements a fully integrated, PLL-free oscillator core using BiCMOS process technology, generating stable frequency directly without feedback loops or external tuning components. Its push-pull CMOS output drives 1kΩ to GND or 500Ω to V+ while maintaining 40–60% duty cycle across supply (2.7V–5.5V) and temperature (-40°C to +125°C).
It eliminates high-impedance nodes and crystal-mounting sensitivity, making it inherently resistant to mechanical shock, board-level EMI, and humidity-induced frequency shift. Startup occurs within 5µs after V+ exceeds 1.65V, and output rise/fall times are tightly controlled at 5ns (CL = 10pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 12MHz nominal - factory-trimmed, no calibration required; matches standard µC/UART clock requirements. |
| Initial Accuracy | ±2% at +25°C - enables reliable boot timing without post-manufacture trimming. |
| Temp Drift | ±100ppm/°C - ensures <±0.12% frequency deviation over full -40°C to +125°C range. |
| Startup Time | 5µs - allows immediate system clock availability after power ramp, reducing reset delay. |
| Supply Range | 2.7V to 5.5V - supports direct interface with 3.3V and 5V logic domains without level shifting. |

| Jitter (16MHz) | 180psP-P - meets timing margin requirements for high-speed serial interfaces (e.g., UART at 3Mbps). |
Pinout & Package
DF3067RX20V is housed in a space-saving 3-pin SC70-3 package (2.0mm × 2.1mm × 0.9mm), optimized for high-density PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 2.7V–5.5V; requires local 0.1µF ceramic bypass to GND for noise immunity. |
| CLOCK | CMOS push-pull clock output | Directly drives µC/UART clock input; no series resistor or termination needed. |
| GND | Ground reference | Must be connected to system ground plane; forms return path for output current. |
Key Features
| Feature | Design Value |
|---|---|
| No external components | Eliminates load capacitors, bias resistors, and feedback networks - reduces BOM count and layout area. |
| Vibration/EMI immunity | Robust operation in harsh environments (e.g., engine control units) due to solid-state design and absence of piezoelectric elements. |
| Rail-to-rail 50% duty cycle | Ensures balanced high/low time for synchronous logic, minimizing setup/hold violations in µC peripherals. |
| Fast 5µs startup | Enables immediate clock availability after power-on, supporting deterministic boot sequences in safety-critical systems. |
| -40°C to +125°C operation | Guaranteed performance across automotive and industrial temperature ranges without derating. |

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-12.000000 | MEMS-based; ±10ppm initial accuracy; 1.62–3.63V supply; 1.2µA standby current | Better accuracy and lower power, but higher cost and longer lead time; requires different footprint (2.0mm × 1.2mm DFN) | Select when ultra-low power or tight frequency tolerance is prioritized over cost and drop-in replacement. |
| ABM3B-12.000MHZ-D2Y-T | Quartz crystal + internal oscillator IC; ±10ppm accuracy; 1.8–3.3V only; 3.5mA typical supply current | Higher EMI susceptibility and mechanical fragility; limited to low-voltage systems; needs external load caps | Choose only if legacy design mandates quartz-based timing or existing layout accommodates 4-pin SMD crystal footprint. |
Compared with DF3067RX20V, SiT1533AI-H4-33E-12.000000 offers superior accuracy and power efficiency but lacks pin compatibility and adds MEMS-specific qualification overhead; ABM3B-12.000MHZ-D2Y-T provides quartz-grade stability but introduces vibration sensitivity and voltage-range limitations - DF3067RX20V balances ruggedness, simplicity, and broad supply compatibility.

FAQ
What is the exact output frequency and tolerance of DF3067RX20V?
The DF3067RX20V is factory-trimmed to deliver a nominal 12MHz output frequency with ±2% initial accuracy at +25°C. Over the full -40°C to +125°C operating range, frequency variation remains within ±0.12% due to its specified ±100ppm/°C temperature coefficient. This makes DF3067RX20V suitable for applications where crystal-level stability is unnecessary but robustness is essential.
Does DF3067RX20V require external load capacitors or biasing components?
No - DF3067RX20V is a fully integrated oscillator requiring zero external components. Unlike quartz crystals or ceramic resonators, it does not need load capacitors, feedback resistors, or gain-setting networks. The only recommended external component is a 0.1µF ceramic bypass capacitor between V+ and GND, placed adjacent to the device to ensure power-supply noise rejection.
Can DF3067RX20V directly drive a microcontroller clock input?
Yes - DF3067RX20V features a rail-to-rail CMOS push-pull output capable of directly driving standard µC clock inputs (e.g., STM32, PIC, or NXP Kinetis families) without level-shifting or series termination. Its ±10mA drive strength supports capacitive loads up to 100pF, and its 40–60% duty cycle meets typical MCU clock input requirements for balanced timing margins.
How does DF3067RX20V perform under mechanical vibration or EMI exposure?
DF3067RX20V exhibits exceptional immunity to vibration and EMI because it contains no piezoelectric elements or high-impedance nodes. Its solid-state BiCMOS oscillator core eliminates microfracture risks associated with quartz crystals and avoids frequency pulling caused by nearby RF fields - validated in automotive-grade testing per AEC-Q200 guidelines for harsh environment operation.
What is the startup behavior of DF3067RX20V after power application?
DF3067RX20V achieves stable clock output within 5µs after V+ rises above 1.65V (at +25°C). For reliable system initialization, it is recommended to assert MCU reset until at least 20µs after V+ exceeds 2.7V. This behavior is consistent across the full supply range (2.7V–5.5V) and temperature range (-40°C to +125°C), making DF3067RX20V ideal for fast-boot embedded systems.
