Product details

Automotive-grade MEMS oscillator

The MEMS base resonator gives it inherent vibration and shock resistance compared to quartz, which matters in drivetrain and chassis-mounted applications.

LVDS output at 125 MHz

LVDS keeps the signal edges clean over short PCB traces — the differential swing reduces radiated EMI and common-mode noise coupling, which is a practical advantage when routing the clock near high-current motor drives or switching regulators.

Wide supply and enable/disable

The supply range spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails without an external regulator.

6-SMD no-lead footprint

Housed in a 5.00 mm x 3.20 mm, 6-pad no-lead package with a seated height of 0.90 mm. The compact footprint and low profile suit space-constrained automotive PCBs — the no-lead construction also reduces parasitic inductance compared to a gull-wing package, preserving signal integrity at 125 MHz.

Frequently asked questions

Is the DSC1123BI1-125.0000 AEC-Q100 qualified?

Yes, the DSC1123BI1-125.0000 carries AEC-Q100 ratings, meaning it meets automotive IC qualification for temperature, reliability stress, and PPAP requirements.

What is the output type of the DSC1123BI1-125.0000?

The output is LVDS (Low-Voltage Differential Signaling), which provides a low-swing differential clock signal suitable for high-speed, low-noise clock distribution.

Does the DSC1123BI1-125.0000 have an enable/disable function?

Yes, the function is Enable/Disable. When disabled, the output goes to high-impedance and supply current drops to 22 mA max.
