| Case | 6-SMD, No Lead |
Holds ±10 ppm frequency stability across the full temperature and voltage range (2.25 V to 3.63 V supply), which is tight enough for 100BASE-TX or SGMII reference clocks without needing a TCXO.
6-SMD no-lead package, 3.20 mm x 2.50 mm body, 0.90 mm seated height — the small footprint leaves room for the LVDS termination resistors and AC-coupling caps near the receiver, keeping the differential trace pair short.
Yes, the oscillator includes an Enable/Disable pin (function per the DSC1123 datasheet). When disabled, the supply current drops from 32 mA max to 22 mA max, allowing power gating in battery-backed or intermittent-duty systems.
