LVPECL output at 156.25 MHz — what it drives
The DSC1102BI2-156.2500T: This is a MEMS-based oscillator delivering a 156.25 MHz LVPECL clock — the standard reference for 10GbE, Fibre Channel, and high-speed serial links. The LVPECL output provides the differential swing and fast edge rates that SERDES inputs require; a single-ended CMOS oscillator would not drive the receiver without external level translation. Supply voltage range is 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without an external regulator. The 58 mA max supply current at 156.25 MHz is typical for a LVPECL output stage at this frequency.
Industrial temperature and standby for field deployment
In a battery-backed design, pulling the enable pin low shuts the clock tree without a separate load switch, saving board space and leakage.
Package and reflow — what the pick-and-place needs
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.90 mm profile is low enough for mezzanine cards and blade servers where board-to-board clearance is tight. Standard surface-mount footprint; no via-in-pad required. Supplied in Tape & Reel (TR) — compatible with automated pick-and-place. Check the MSL rating before the reflow profile; a MEMS oscillator typically carries MSL 1 or 2, but verify the label on the reel to avoid moisture-related popcorning in the oven.
