The supply voltage accepts 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails without an extra regulator; the 32 mA max active current is modest for a 125 MHz differential output.
Housed in a 7.00 mm × 5.00 mm 6-SMD package with no lead exposed pad, the footprint matches standard 7×5 mm oscillator land patterns — the 0.90 mm seated height keeps it low-profile for mezzanine card clearance.
This part is Active and sourced to order through independent distribution. Submit an RFQ with your target quantity and we will confirm current pricing and lead time — no stock-holding claim, real-time confirmation at quote.
LVDS — a differential pair that rejects common-mode noise and delivers a clean 125 MHz clock to receivers with on-chip 100 Ω termination.
Yes, a Standby (Power Down) pin drops the supply current to 95 µA max, letting the system shut down the oscillator between active periods.
The base product number DSC1103 covers both variants, but the suffix (AI1 vs AI2) may indicate different stability or temperature options — confirm the exact spec against your BOM before substituting.
