Product details

125 MHz LVDS clock source with standby control

Its 2.5V to 3.3V supply range covers common digital rails, and the standby (power down) function pulls the disable current to 5 µA max — useful for gated clock domains or sleep-mode power budgets where the oscillator must be stopped without removing the supply.

Microchip lists the DSC1203NI3-125M0000 as Active.

6-VDFN package — board layout notes

The 6-VDFN package measures 7.00mm x 5.00mm with a seated height of 0.90mm max. Surface-mount, tube delivery. The 6-pin layout has no exposed thermal pad; decoupling to the supply pins follows standard high-speed oscillator practice — a 100 nF ceramic close to each supply pin, with a bulk capacitor on the input rail. The standby pin (pin 1 on the standard DSC12xx footprint) should be pulled low for normal operation; leave it high or floating to hold the part in power-down.

Frequently asked questions

Is DSC1203NI3-125M0000 compatible with 3.3V systems?

Yes. It operates over 2.5V to 3.3V, so a 3.3V supply is within the specified range. The LVDS output is compatible with standard 3.3V LVDS receivers.

What is the DSC1203NI3-125M0000's standby function?

The standby (power down) function disables the output and reduces supply current to 5 µA max. When the standby pin is asserted, the oscillator stops; de-asserting it restarts within the typical start-up time of the MEMS resonator (microseconds). This is useful for battery-powered or duty-cycled designs where the clock can be gated.
