Product details

It delivers a standard XO function with an Enable/Disable control pin, drawing 32 mA max from a 2.25V to 3.63V supply.

AEC-Q100 qualification and package footprint

The 6-SMD, no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that fits tight PCB layouts in camera modules or radar sensor boards. The LVDS output provides differential signaling with low EMI, which simplifies layout in mixed-signal designs where clock noise couples into analog front-ends.

MEMS vs quartz: what the stability spec means for your BOM

For a 200 MHz LVDS clock feeding a SerDes or FPGA, this translates to a worst-case timing error of roughly 5 ps at the receiver — well within the setup-and-hold margin of most automotive-grade FPGAs and Ethernet PHYs. Unlike a quartz oscillator, the MEMS resonator does not require a load capacitor or external feedback resistor, reducing BOM count by two passives per clock tree.

Frequently asked questions

Is the DSC1123DL2-200.0000T obsolete?

No. The product status is Active.

Can the DSC1123DL2-200.0000T replace a quartz oscillator?

Yes, in most applications. The MEMS resonator provides equivalent or better frequency stability (±25 ppm) over temperature and supply voltage, with higher shock and vibration immunity. The 6-SMD footprint is compatible with standard quartz oscillator land patterns, but verify the Enable/Disable logic polarity and the supply voltage range (2.25V to 3.63V) against your existing quartz part's specifications.

Is the DSC1123DL2-200.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. This qualification is required for under-hood and chassis-domain automotive electronics.

What is the output type of the DSC1123DL2-200.0000T?

LVDS (Low-Voltage Differential Signaling) output. LVDS provides low EMI, high noise immunity, and supports the 200 MHz clock rate over short PCB traces without a separate termination resistor — the differential pair is self-terminating at the receiver.
