Product details

77 MHz LVPECL MEMS oscillator — active production, ±10 ppm stability

The MEMS base resonator replaces a quartz crystal — the part is a complete oscillator in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm, with a seated height of 0.90 mm. Supply voltage spans 2.25 V to 3.6 V, making it compatible with 2.5 V and 3.3 V logic rails without an external regulator.

LVPECL output and enable/disable function

The LVPECL output provides the differential swing and fast edge rates required for high-speed clock distribution to FPGAs, SERDES, or Ethernet PHYs — the 58 mA max supply current reflects the output driver's bias current.

Frequently asked questions

Is the DSC1122CE5-077.0000T a direct replacement for the DSC1122CE5-077.0000?

The base product number DSC1122 is shared, and the suffix 'T' typically denotes Tape & Reel packaging. The electrical characteristics — 77 MHz, LVPECL, ±10 ppm, 2.25-3.6 V supply — are identical. The 'T' suffix does not change the functional fit; verify the reel quantity matches your BOM line.
