Product details

148.5 MHz LVDS clock from a MEMS resonator

Supply flexibility and enable/disable control

The supply range spans 2.25V to 3.63V, so the same order code works on a 2.5V or 3.3V rail without a separate LDO — the internal regulation handles the difference.

No last-time-buy window or successor has been announced.

6-SMD package and board layout

The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many LVDS oscillators in this form factor.

Frequently asked questions

Can the DSC1123AI5-148.5000T operate from a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.63V, so 3.3V is well within the operating window.

What is the frequency stability of the DSC1123AI5-148.5000T?

The frequency stability is ±10 ppm over the operating temperature range.
