Product details

The DSC1001DL2-049.5000T delivers a 49.5 MHz clock output in CMOS logic levels, with ±25 ppm frequency stability across the full operating range.

Supply voltage range of 1.8V to 3.3V covers the common logic rails — no external level translator needed when moving between a 1.8V MCU and a 3.3V peripheral clock input. The 4-VDFN package (2.50 mm × 2.00 mm, 0.90 mm seated height) is a standard land-grid array footprint; the 0.50 mm pitch pads require a 4-layer PCB for fan-out only if the inner rows are used, but the outer rows break out cleanly on a 2-layer board for most layouts.

Frequently asked questions

What is the frequency of the DSC1001DL2-049.5000T?

49.5 MHz, with CMOS output and ±25 ppm frequency stability.

What does the Standby (Power Down) function do?

When the standby pin is asserted, the oscillator stops output and draws 15 µA max (disable current) — useful for battery-powered or sleep-mode systems that need to shut down the clock tree.

What are alternatives to the DSC1001DL2-049.5000T in the same family?

The DSC1001 series includes other frequency and stability variants in the same 4-VDFN package; the base product number DSC1001 covers the family. For a pin-compatible alternative with a different frequency, check the DSC1001 series ordering codes.
