Product details

125 MHz LVDS clock for FPGA and SERDES reference

LVDS differential signalling keeps the edge jitter low over short PCB traces, which matters when the clock fans out to multiple SERDES lanes or a clock-tree buffer.

The 2.25V to 3.63V supply range covers both 2.5V and 3.3V rails without an intermediate regulator — a single rail powers the oscillator and the downstream logic.

Enable/Disable function and package footprint

Housed in a 7.00 mm × 5.00 mm 6-SMD package with an exposed pad, the footprint matches industry-standard 7×5 mm ceramic and plastic oscillators, simplifying board layout reuse.

Frequently asked questions

What is the output type of DSC1123AI1-125.0000T?

The output is LVDS (Low-Voltage Differential Signaling), a differential pair that provides low noise and fast edges for high-speed clock distribution.

What supply voltages can DSC1123AI1-125.0000T run on?

It operates over a 2.25V to 3.63V range, covering both 2.5V and 3.3V rails. No external LDO is needed if the rail is within that window.

Does DSC1123AI1-125.0000T have an enable/disable function?

Yes, the Enable/Disable pin allows the output to be tri-stated. This is useful for power gating the clock in low-power sleep states.
