Product details

An OEM auditor will expect PPAP documentation; the AEC-Q100 mark gives you the starting evidence.

Frequency stability and supply range for a clean clock

For a 56.75 MHz clock, ±25 ppm means the output stays within ±1419 Hz of the nominal frequency across temperature. 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.

Frequently asked questions

What is the difference between DSC1001BI2-056.7500 and DSC1001BI2-050.0000?

The only difference is the output frequency: 56.75 MHz vs 50.0000 MHz. 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.

Is the DSC1001BI2-056.7500 a direct replacement for a quartz crystal oscillator in the same footprint?

It is pin-compatible with standard 5.0 mm × 3.2 mm 4-pad SMD oscillators — the same 0.197" × 0.126" footprint. The MEMS die inside is drop-in compatible with the quartz oscillator it replaces, provided the supply voltage (1.8 V to 3.3 V) and output type (CMOS) match the existing circuit. No board spin is required.
