Product details

The LVDS signalling delivers the low-jitter, differential edge rates required for 200 MHz clock distribution in high-speed serial links — think PCIe Gen 2, Gigabit Ethernet, or automotive video interfaces.

Supply voltage spans 2.25V to 3.63V, covering both 2.5V and 3.3V rails without an intermediate regulator. For a 200 MHz clock, ±50 ppm translates to a ±10 kHz absolute frequency error — well within the capture range of most SERDES PLLs.

Package and board layout note

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

How can I order the DSC1123AI1-200.0000 or check availability?

No stock-holding claim is made here; each order is sourced through our independent distribution channel.

What is the difference between the DSC1123AI1-200.0000 and a standard 200 MHz crystal oscillator?

A standard quartz crystal oscillator uses a piezoelectric quartz resonator; the DSC1123 uses a MEMS resonator. MEMS oscillators typically offer better shock and vibration resistance, faster start-up, and smaller package options. The LVDS output is differential, which provides better noise immunity over long PCB traces compared to a single-ended CMOS oscillator.

Is the DSC1123AI1-200.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, qualifying it for automotive applications.
