Product details

Supply voltage spans 2.25V to 3.63V, letting it run from a 2.5V or 3.3V rail without an extra regulator, and max supply current is 32 mA — the LVDS output stage draws the bulk of that, so the thermal budget in a dense board is manageable.

When the standby pin is asserted, the LVDS output goes high-impedance, so the receiver sees a floating input — the downstream logic must handle that state or pull the line to a known level.

Housed in a 6-SMD No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a compact footprint that fits under a mezzanine card or alongside a BGA without crowding the keep-out zone. Surface-mount on standard FR-4 with the same land pattern as many 3.2 x 2.5 mm MEMS oscillators; no special via-in-pad or thermal relief needed for the 32 mA draw.

Frequently asked questions

How does the standby function work on the DSC1103CI5?

The Standby (Power Down) function reduces supply current to 95 µA max and puts the LVDS output into high-impedance state.
