Product details

The 200 MHz LVDS output drives point-to-point clock distribution for high-speed serial interfaces like Gigabit Ethernet, PCIe, and SATA without an external fanout buffer. The 2.25V to 3.63V supply range lets it run from a 2.5V or 3.3V rail without a separate regulator, simplifying the power tree.

Enable/Disable control for power-sensitive designs

For a battery-backed ECU that sleeps 90% of the time, that 10 mA reduction across four oscillators saves 36 mA·hours per day.

Package and board-level integration

The 6-SMD, No Lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm footprint that matches many quartz oscillators, so a board designed for a quartz XO can often accept this MEMS part without a layout change. The 0.90 mm height clears typical 1.0 mm keep-out zones under shrouded headers or mezzanine connectors.

Frequently asked questions

Is the DSC1123BI5-200.0000 AEC-Q100 qualified?

Yes, the DSC1123BI5-200.0000 is rated AEC-Q100, meaning it has passed automotive-grade stress tests for temperature cycling, ESD, latch-up, and extended life. It is suitable for under-hood and cabin automotive applications.

What is the output type and frequency of the DSC1123BI5-200.0000?

The output is LVDS at 200 MHz. LVDS provides low-voltage differential signaling with common-mode rejection, making it suitable for driving high-speed serial interfaces over short PCB traces without a separate clock buffer.

Does the DSC1123BI5-200.0000 have an enable/disable function?

Yes, the DSC1123BI5-200.0000 includes an Enable/Disable function. When disabled, the output goes to high-impedance and supply current drops from 32 mA max to 22 mA max, saving power in sleep or standby modes.
