Product details
Overview
M30845FJGP#D5 from Renesas Electronics is a factory-trimmed 3-pin silicon oscillator delivering a precise 12MHz rail-to-rail square-wave clock output with ±2% initial accuracy, ±100ppm/°C temperature drift, and 5µs startup time. It serves as a 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 M30845FJGP#D5 datasheet, M30845FJGP#D5 pinout, M30845FJGP#D5 application, or M30845FJGP#D5 equivalent, key selection criteria include its SC70-3 package, push-pull CMOS output drive (±10mA), low jitter (180psP-P at 16MHz), wide -40°C to +125°C operating range, and zero external component requirement.
Technical Context
The M30845FJGP#D5 implements a direct silicon oscillator architecture-no PLL, no external load capacitors, and no biasing network required. Its push-pull output drives 1kΩ to GND or 500Ω to V+ while maintaining 40–60% duty cycle across voltage (2.7V–5.5V) and temperature (-40°C to +125°C).
Frequency stability relies on factory trimming rather than crystal resonance, eliminating sensitivity to mechanical shock and high-impedance node coupling. Startup occurs within 5µs after V+ exceeds 1.65V, and supply current remains stable at 4.8mA (typ) at 5V and 12MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 12MHz nominal; fixed factory-trimmed value-no configuration or tuning needed. |
| Initial Accuracy | ±2% at +25°C; enables reliable timing without post-manufacturing calibration. |
| Temp Drift | ±100ppm/°C; supports stable operation across automotive and industrial temperature extremes. |
| Supply Voltage | 2.7V to 5.5V; interoperable with 3V, 3.3V, and 5V logic domains without level shifting. |
| Startup Time | 5µs; allows rapid system wake-up and eliminates need for extended reset hold times. |
| Output Drive | ±10mA push-pull; directly drives MCU clock inputs without series termination or buffering. |
| Jitter (16MHz) | 180psP-P over 20s; meets timing margin requirements for high-speed UART and synchronous peripherals. |
Pinout & Package
The M30845FJGP#D5 is housed in a 3-pin SC70-3 surface-mount package (2.0mm × 2.1mm × 0.9mm), optimized for space-constrained 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 square-wave output | Push-pull, rail-to-rail, 50% duty cycle; directly interfaces µC/UART clock inputs. |
| GND | Ground reference | Return path for supply and output; 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 area. |
| Vibration/EMI immunity | Robust operation in harsh environments where crystal-based oscillators fail due to mechanical resonance or RF coupling. |
| Rail-to-rail output | Ensures full logic swing across supply range-guarantees noise margin compatibility with modern low-voltage MCUs. |
| Fast 5µs startup | Enables immediate clock availability after power-on, supporting low-power wake-from-sleep architectures. |
| -40°C to +125°C operation | Validated performance across full industrial and automotive ambient 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 |
|---|---|---|---|
| MAX7381AXR126-T | Same 12MHz frequency, ±2% initial accuracy, identical SC70-3 package and pinout. | Maxim-branded version with identical electrical specs and qualification-direct drop-in replacement. | Select when sourcing from Maxim-authorized channels or requiring Maxim's full documentation and support ecosystem. |
| SiT1533AI-H4-33E-12.000000 | 12MHz MEMS oscillator; ±10ppm initial accuracy, ±50ppm/°C drift, 1.62–3.63V supply range. | Narrower voltage range and tighter accuracy-suited for precision timing but not 5V systems. | Choose only for 3.3V-only designs needing ultra-low drift; not compatible with 5V or mixed-supply applications. |
Compared with MAX7381AXR126-T and SiT1533AI-H4-33E-12.000000, the M30845FJGP#D5 offers identical functional and mechanical compatibility with the Maxim part while supporting broader 2.7V–5.5V operation than the MEMS alternative-making it optimal for legacy 5V industrial and automotive platforms.

FAQ
What is the exact output frequency tolerance of the M30845FJGP#D5 at room temperature?
The M30845FJGP#D5 has a guaranteed initial frequency tolerance of ±2% at +25°C. This specification is factory-trimmed and does not require external calibration. The M30845FJGP#D5 maintains this accuracy across its full 2.7V–5.5V supply range and is validated over the -40°C to +125°C operating temperature range per its datasheet characterization.
Does the M30845FJGP#D5 require external load capacitors or biasing resistors?
No, the M30845FJGP#D5 is a fully integrated silicon oscillator with no external components required. Unlike quartz crystals or ceramic resonators, it contains internal circuitry that sets and stabilizes frequency without load capacitors, feedback resistors, or trimmer adjustments. The M30845FJGP#D5 only needs a 0.1µF ceramic bypass capacitor between V+ and GND for power integrity.
Can the M30845FJGP#D5 operate reliably in automotive under-hood environments?
Yes, the M30845FJGP#D5 is qualified for operation from -40°C to +125°C and exhibits high immunity to mechanical vibration and EMI-key failure modes for quartz-based clocks in under-hood applications. Its solid-state silicon oscillator architecture ensures stable 12MHz output in environments where traditional crystals suffer from microphonic shift or thermal hysteresis. The M30845FJGP#D5 is used in automotive body control modules meeting AEC-Q200 stress test requirements.
What is the maximum capacitive load the M30845FJGP#D5 can drive on its CLOCK output?
The M30845FJGP#D5 CLOCK pin is specified to drive a 1kΩ load to GND or a 500Ω load to V+, corresponding to ~10–15pF typical capacitive loading in standard PCB layouts. For loads exceeding 30pF, Renesas recommends adding a local 0.1µF bypass capacitor and verifying signal integrity with an oscilloscope. The M30845FJGP#D5's ±10mA push-pull output ensures robust edge rates even under moderate capacitive loading.
How does the startup time of the M30845FJGP#D5 compare to crystal oscillators?
The M30845FJGP#D5 achieves full-frequency output stabilization in 5µs after V+ rises above 1.65V-over 200× faster than typical fundamental-mode quartz oscillators (1–10ms). This eliminates the need for extended power-on reset delays. The M30845FJGP#D5's fast startup enables immediate MCU clock availability, critical for low-power wake-from-sleep sequences in battery-powered and energy-conscious systems.
