Product details

175 MHz LVDS clock source for high-speed signal chains

The LVDS swing keeps jitter low over the 7.0 mm × 5.0 mm 6-SMD footprint.

Supply voltage tolerance and power-down gating

The wide 2.25V to 3.63V supply range lets this oscillator run from a 2.5V or 3.3V rail without an intermediate LDO — one less component in the power tree. The Enable/Disable function gates the LVDS output without removing power — useful for sequencing multiple clock domains during system sleep or for suppressing the clock during board-level debug to isolate noise sources.

Frequently asked questions

Is the DSC1123AI5-175.0000 compatible with my existing PCB layout?

The 6-SMD package with exposed pad is a standard 7.0 mm × 5.0 mm footprint used across many MEMS and quartz oscillators. Confirm the pad layout matches the datasheet mechanical drawing — the exposed pad should be soldered to a ground plane for thermal management, though the 32 mA max draw keeps self-heating low.
