The DSC6001HL2B-026.0000 is a 26 MHz MEMS-based oscillator from Microchip's DSC60XX series, delivering a CMOS output with ±25 ppm frequency stability across temperature and supply variation.
Operating from 1.71 V to 3.63 V, this oscillator runs directly off a 1.8 V or 3.3 V rail without an extra LDO — the 1.71 V floor covers a 1.8 V rail with 90 mV of headroom, and the 3.63 V ceiling gives margin above a nominal 3.3 V.
Package and footprint — 4-VFLGA layout notes
Housed in a 4-VFLGA package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm, this is a compact surface-mount oscillator that fits under a shielding can or on a dense mixed-signal board. The 4-pin land-grid array requires a via-in-pad or microvia fan-out for the supply and output traces — the small pitch means the PCB layout should follow the recommended footprint in the datasheet to avoid solder-bridging.
