That is tight enough for a CAN-FD or FlexRay controller that expects a 0.5% clock tolerance; it is also tight enough for a high-speed serial data link (e.g., 100BASE-T1) where the PLL jitter budget is single-digit picoseconds. At 56.75 MHz, the output transition time is a fraction of the period, keeping the clock edge clean for the downstream flip-flop setup/hold window. ## Standby power-down and current draw The 7.2 mA max operating current at 56.75 MHz is low for a MEMS oscillator at this frequency; a comparable quartz-based oscillator often draws 10–15 mA. The savings add up in a multi-clock ECU. Product status is Active. The DSC1001 series is a current production line from Microchip.","metaTitle":"DSC1001BI2-056.7500 MEMS XO – 56.75 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001BI2-056.7500: 56.75 MHz XO (Standard), CMOS output, ±25 ppm, AEC-Q100, -40°C to 85°C, 7.2 mA max.

Both are in the DSC1001 series, share the same package (4-SMD, No Lead), same CMOS output, same ±25 ppm stability, same AEC-Q100 qualification, and same operating temperature range. The BOM must specify the exact frequency; a 50 MHz oscillator will not lock a PLL tuned for 56.75 MHz."},{"question":"Is the DSC1001BI2-056.7500 a direct replacement for a quartz crystal oscillator in the same footprint?","answer":"It is pin-compatible with standard 5.0 mm × 3.2 mm 4-pad SMD oscillators — the same 0.197\" × 0.126\" footprint.
