Product details

The DSC1123CI5-180.0000 is an active-production MEMS-based XO delivering a 180 MHz LVDS clock from a 2.25V to 3.63V supply rail.

The wide 2.25V~3.63V supply tolerance means it can run directly from a 2.5V or 3.3V rail without an intermediate LDO, simplifying the power tree in dense automotive PCBs.

Enable/Disable function and disable current

This is useful in automotive modules that must meet ignition-off quiescent current budgets — the disable state still draws power, so a load switch ahead of the oscillator may be needed for sub-milliamp sleep modes.

Housed in a 6-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1123CI5-180.0000 is a surface-mount component that reflows with standard lead-free profiles.

Frequently asked questions

Is the DSC1123CI5-180.0000 AEC-Q100 qualified and can it be used in automotive applications?

Yes, the DSC1123CI5-180.0000 is rated AEC-Q100, which qualifies it for automotive-grade reliability stress and temperature cycling.

What is the output type of the DSC1123CI5-180.0000?

The output is LVDS (Low-Voltage Differential Signaling), which provides a differential 180 MHz clock with low electromagnetic interference and high noise immunity — ideal for routing over longer PCB traces in automotive or industrial backplanes.

Does the DSC1123CI5-180.0000 have an enable/disable function?

Yes, it includes an Enable/Disable function. When disabled, the maximum supply current drops from 32 mA to 22 mA, allowing the system to reduce power consumption when the clock is not required.

Can the DSC1123CI5-180.0000 replace a standard crystal oscillator?

It can replace a quartz-based XO in a 6-pin no-lead footprint, provided the application requires LVDS levels and can tolerate the MEMS-based start-up characteristics. The MEMS resonator is more shock and vibration tolerant than quartz, which is an advantage in automotive and industrial environments, but the output type and supply voltage must match the downstream clock receiver.
