312.5 MHz LVDS clock — why the output type matters
The DSC1123AI2-312.5000: This is a standard XO with LVDS output, not single-ended — at 312.5 MHz the differential pair keeps signal integrity over longer PCB traces and reduces radiated EMI compared to a CMOS clock at the same frequency.
Automotive-grade MEMS — AEC-Q100 and temperature range
Operates from 2.25 V to 3.63 V — covers the common 2.5 V and 3.3 V logic rails without an external LDO. The 32 mA max supply current is the total draw including the output buffer. 6-SMD package with exposed pad, 7.00 mm x 5.00 mm body, 0.90 mm seated height — the exposed pad needs a thermal via pattern under the part for heat sinking; the pad is tied to ground on the PCB.
