MEMS oscillator with LVDS output at 54 MHz
The DSC1123DE2-054.0000T is a 54 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1123 series, delivering an LVDS output — a differential signal that rejects common-mode noise better than a single-ended CMOS clock, which matters when the trace runs past a switching regulator or a high-current motor drive. Frequency stability is held to ±25 ppm across the -20°C to 70°C operating range, so the clock edge jitter stays within the timing budget for a 100BASE-TX Ethernet PHY or a CAN-FD controller without external PLL re-centering.
AEC-Q100 qualification and supply range
The supply voltage spans 2.25 V to 3.63 V, letting it run from a 3.3 V or 2.5 V rail without an extra LDO.
Housed in a 6-SMD, no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the compact footprint suits space-constrained PCBs in ADAS cameras or telematics modules. Surface-mount reflow follows standard lead-free profiles.
