ASFLMB-100.000MHZ-LR-T 概要
A MEMS oscillator is a silicon-based timing device that replaces legacy quartz crystals with a micro-electromechanical resonator, offering superior shock and vibration immunity, faster startup, and tighter stability than comparable quartz units at similar cost. In the component taxonomy, MEMS oscillators sit within crystal oscillators -> oscillators -> frequency control components -> timing devices. MEMS resonators are manufactured in standard semiconductor processes, enabling finer lot-to-lot consistency and enabling integration of the oscillator circuitry on the same silicon die.
Key differentiating features of the ASFLMB series include ±25 ppm total stability (which includes post-reflow, temperature, load and supply variation per the manufacturer datasheet), an industry-standard 4-pad SMD footprint with no mechanical rotate, and low-jitter performance suitable for networking and FPGA reference-clock applications. According to the Abracon datasheet, the part is offered across 1.5 MHz to 110 MHz frequency options with multiple stability grades.
Typical applications include Ethernet switch and router reference clocks, FPGA/SoC primary reference inputs, industrial controller timing, USB 2.0/3.x high-speed interfaces, and portable battery-powered instruments requiring a low-power standby mode. The wide 1.8V-3.3V supply supports direct connection to common MCU rails without level shifting.
When designing with this part, place a 0.01 µF bypass capacitor between pin 2 (GND) and pin 4 (VDD) as recommended in the manufacturer datasheet, and route the output trace with 50 Ω characteristic impedance for best edge fidelity.

主な用途
ASFLMB-100.000MHZ-LR-T の用途: 7 件s: FPGA / SoC Reference Clock, Ethernet Switch / Router Clock, Industrial Controller Timing, Portable / Battery-Powered Instrument, USB 2.0 High-Speed Interface, Test & Measurement Front-End, LED Display Controller Timing.
FPGA / SoC Reference Clock
The ASFLMB-100.000MHZ-LR-T provides a 100 MHz LVCMOS reference directly to FPGA and SoC primary clock inputs (e.g., Xilinx 7-series MRCC, Microchip PolarFire REF_CLK). The ±25 ppm total stability and 1.8-3.3 V supply align with common FPGA bank voltages, eliminating level shifters. Pin 1 standby lets system firmware gate the oscillator to save quiescent current when the FPGA is held in reset. According to the Abracon datasheet, the wide supply range supports both 1.8 V Zynq-7000 and 3.3 V Cyclone V bank connections from a single BOM line.
おすすめ
Ethernet Switch / Router Clock
The ASFLMB-100.000MHZ-LR-T supplies the 100 MHz reference required by 100 Mbps / 1 Gbps Ethernet PHYs and switches such as the KSZ9893. MEMS-based 5032 oscillators offer better vibration tolerance than legacy quartz, fitting fanless switch housings and PoE-powered edge devices. The 1.8-3.3 V supply covers both 1.0 V PHY cores (via local LDO) and 2.5/3.3 V MAC rails. Standby mode supports Energy-Efficient Ethernet (EEE) LPI states by gating the reference when the PHY enters low-power idle, per the Abracon datasheet.
おすすめ
Industrial Controller Timing
Industrial PLCs and motor controllers running on -40°C to +85°C environments use the ASFLMB-100.000MHZ-LR-T as a system clock for backplane synchronization, ADC sampling, and PWM generation. The ±25 ppm stability over the full industrial temperature range keeps serial-baud and CAN-FD timing within specification without per-board trimming. The 5032 surface-mount package and 0.9 mm profile fit dense control-board layouts where vertical clearance above the PCB is limited, per Abracon dimensional drawings.
おすすめ
Portable / Battery-Powered Instrument
The ASFLMB-100.000MHZ-LR-T standby (power-down) function on pin 1 makes it suitable for handheld test gear, portable medical instruments, and IoT endpoints that must minimize quiescent draw. According to the Abracon ASFLMB datasheet, the standby pin disables the LVCMOS output when asserted, allowing the system MCU to gate the reference clock during sleep states and wake on interrupts. Wide 1.8-3.3 V support covers single-cell Li-ion (3.0-4.2 V via LDO) and coin-cell designs.
おすすめ
USB 2.0 High-Speed Interface
USB 2.0 high-speed PHYs and certain USB 3.0 companion controllers require a 100 MHz LVCMOS reference for their internal PLLs. The ASFLMB-100.000MHZ-LR-T provides this with low jitter for clean 480 Mbps signaling. The 5032 SMD package drops onto standard USB hub reference-clock footprints, and the 1.8-3.3 V range covers both VL and VBUS-derived rails. The standby pin supports USB suspend states per the USB specification.
おすすめ
Test & Measurement Front-End
Bench instruments, data loggers, and ATE systems use the ASFLMB-100.000MHZ-LR-T to clock high-speed ADCs, DACs, and FPGA DSP pipelines where absolute timing matters. The ±25 ppm stability and 1.8-3.3 V supply pair with 16-24 bit SAR ADCs and direct-digital synthesis ICs. MEMS construction gives improved vibration immunity versus quartz, which is useful for portable test platforms in field service environments, per the manufacturer datasheet.
おすすめ
LED Display Controller Timing
Multi-panel LED video walls and digital signage controllers use the ASFLMB-100.000MHZ-LR-T to provide a stable reference for HDMI/DVI pixel clocks and FPGA-based refresh logic. The 5032 footprint fits narrow panel-PCB strips, and the 1.8-3.3 V supply aligns with common LED driver rails. MEMS resilience to mechanical stress reduces field failures in vibration-prone installations such as outdoor signage.

設計ノート
Per the Abracon ASFLMB datasheet, place a 0.01 µF X7R ceramic bypass capacitor directly between pin 2 (GND) and pin 4 (VDD), keeping the trace length under 2 mm to suppress supply-noise coupling into the LVCMOS output. Use a continuous ground plane under the package and avoid routing signal traces between the oscillator and its load - keep the output trace short with 50 Ω characteristic impedance for clean edges above 50 MHz.
Isolate the ASFLMB-100.000MHZ-LR-T from switching converters and noisy digital buses by placing it on a quiet area of the PCB near the load pin. MEMS oscillators are less susceptible to vibration than quartz but still benefit from a mechanically stable mounting. Avoid running high-current traces under or near the 5032 footprint to prevent ground-bounce modulation of the output.
Do not leave pin 1 (STDBY) floating - per the manufacturer datasheet it must be tied to VDD for normal operation, or driven by a GPIO for power-down control. Floating pin 1 can cause unpredictable output states and higher-than-typical current draw. Also confirm the receiver logic family's VIL/VIH matches the LVCMOS swing at the chosen VDD level (e.g., 1.8 V LVCMOS does not reliably drive a 3.3 V CMOS input).
At 100 MHz LVCMOS, harmonic content extends beyond 500 MHz; series-terminate the output with a 33 Ω resistor placed within 5 mm of the oscillator pin when driving long traces (>25 mm) or capacitive loads (>15 pF). For point-to-point loads within 10 mm, no series resistor is typically needed. Verify rise/fall time against the receiver's setup/hold budget.
