Product details

The DSC1001BE2-050.0000T is a 50 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 qualification makes this oscillator suitable for automotive cabin and body electronics, where the MEMS resonator's shock and vibration tolerance exceeds that of quartz crystal oscillators.

Operating from a 1.8V to 3.3V supply rail, the oscillator can be powered directly from a 1.8V MCU I/O bank or a 3.3V peripheral rail without an external regulator.

Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1001BE2-050.0000T is a surface-mount oscillator compatible with standard reflow soldering profiles.

Frequently asked questions

Is the DSC1001BE2-050.0000T AEC-Q100 qualified?

Yes, the DSC1001BE2-050.0000T carries AEC-Q100 qualification, making it suitable for automotive applications within its -20°C to 70°C temperature range. This qualification covers the reliability stress and temperature grade requirements typical for cabin and body electronics.

What is the frequency tolerance of the DSC1001BE2-050.0000T?

The frequency stability is specified at ±25 ppm across the operating temperature range. This is a standard tolerance for automotive and industrial clock applications such as CAN, Ethernet, or MCU reference clocks.

Can the DSC1001BE2-050.0000T replace a standard crystal oscillator?

Yes, the DSC1001BE2-050.0000T is a drop-in replacement for many quartz crystal oscillators in the same 4-SMD package and pinout, provided the supply voltage (1.8V to 3.3V) and CMOS output are compatible. The MEMS resonator offers improved shock and vibration tolerance compared to quartz.

What is the standby current of the DSC1001BE2?

When the standby (power-down) function is enabled, the maximum supply current is 15 µA. This low quiescent draw supports battery-powered or sleep-mode designs where the oscillator is disabled between active periods.
