ASDMB-100.000MHZ-LY-T 개요
A MEMS oscillator is a silicon-based timing device that replaces traditional quartz crystal oscillators with a silicon MEMS resonator and a Phase-Locked Loop (PLL) synthesizer on the same silicon die. Compared to quartz, MEMS oscillators provide superior shock and vibration resistance, better long-term aging characteristics, faster startup, and lower power consumption. The ASDMB Series combines an Abracon-branded Pure Silicon MEMS resonator with an integrated ASIC, housed in an ultra-miniature 2520 SMD package — making it part of the broader clock oscillator -> frequency control -> timing IC -> semiconductor device hierarchy. The 2520 footprint is one of the smallest standard oscillator packages, enabling compact PCB layouts in space-constrained designs.
Key features include 100 MHz nominal frequency with ±10 ppm stability over the full -40°C to +85°C industrial operating range, wide 1.8 V / 2.5 V / 3.3 V supply compatibility, low 16 mA typical supply current, integrated standby (power-down) pin for power gating, 15 pF LVCMOS output drive at 55% symmetry, and RoHS/RoHS II compliance. The MEMS construction provides superior shock and vibration immunity compared to quartz alternatives.
Architecturally, the ASDMB series combines Abracon's Pure Silicon MEMS resonator with a programmable ASIC PLL synthesizer, eliminating the need for external load capacitors required by bare crystal resonators. This integration delivers tighter frequency stability, faster production lead times, and short lead times for industrial and consumer designs compared to legacy quartz XOs.
Typical applications include Ethernet PHY clocking, networking switches and routers, FPGA and processor reference clocks, industrial automation, and consumer electronics requiring a stable 100 MHz reference. The 2520 package fits space-constrained layouts in IoT endpoints, SSDs, and high-density networking line cards.
When designing with this part, place the standby pin through a 10 kΩ pull-up to VDD for always-on keep power operation, or drive it low for power-down (≤10 µA typ). Maintain clean supply decoupling with a 0.1 µF ceramic capacitor adjacent to the VDD pin. The 4-pad SMD2520 footprint requires standard reflow profile per JEDEC J-STD-020.

설계 노트
Place the ASDMB-100.000MHZ-LY-T as close as possible to the receiver's clock input pin to minimize trace length and reflections. Per Abracon's ASDMB series datasheet, route the LVCMOS output over an impedance-controlled 50 Ω trace with a series 33 Ω damping resistor placed near the oscillator output; this reduces overshoot/undershoot on fast edges into capacitive loads.
Decouple the VSD pin (pin 4) with a 0.1 µF X7R ceramic placed within 2-5 mm of the IC, plus a bulk 10 µF tantalum or ceramic capacitor on the same supply rail. The ASDMB datasheet specifies 16 mA typical supply current at 3.3 V; insufficient decoupling can cause jitter and frequency instability.
Avoid placing the ASDMB-100.000MHZ-LY-T adjacent to noisy switching regulators or high-current traces. Per Abracon's ASDMB datasheet, the MEMS resonator can pick up EMI from nearby switchers - keep at least 5 mm separation or use a ground guard trace around the oscillator footprint on outer layers.
Do not leave the standby pin floating - it has an internal pull-up but noise on the pin can cause intermittent output disable. The ASDMB datasheet recommends tying ST to VSD through a 10 kΩ pull-up for always-on keep power operation; drive low only when intentional power-down is desired.
