Product details

155.52 MHz LVPECL MEMS oscillator — industrial temperature grade

Supply voltage and output logic — LVPECL clocking

Runs on a 2.25V to 3.6V supply rail, so it fits both 2.5V and 3.3V clock domains without an extra regulator. The LVPECL output delivers the differential swing needed for high-speed serial links (Gigabit Ethernet, Fibre Channel, SONET) — the 155.52 MHz frequency is a standard telecom rate, and the 58 mA max supply current is the budget for the output stage driving a 50-Ω terminated line.

Package and footprint — 7.0 × 5.0 mm no-lead

Housed in a 6-SMD, no-lead exposed pad package measuring 0.276" × 0.197" (7.00 mm × 5.00 mm) with a seated height of 0.035" (0.90 mm).

Frequently asked questions

Can DSC1122AI5-155.5200T replace other 155.52 MHz oscillators?

It is a direct functional replacement for any 155.52 MHz LVPECL oscillator in the same 7.0 × 5.0 mm 6-pin footprint, provided the supply voltage and enable polarity match. The MEMS base gives better shock immunity and faster startup than quartz equivalents.
