156.25 MHz MEMS clock for PCIe and 10GbE reference
The DSC1124CI1-156.2500TA is a fixed-frequency MEMS oscillator delivering 156.25 MHz with an HCSL output — the standard clock format for PCIe Gen1/2/3 and 10GbE SerDes reference inputs. Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator.
The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCIe card layouts and small-form-factor designs.
