156.25 MHz LVPECL — clock tree fit and signal integrity
The DSC1122CI1-156.2500 delivers a 156.25 MHz LVPECL output from a MEMS resonator — a frequency commonly used in 10 Gigabit Ethernet and PCIe Gen 3 reference clocks.
MEMS resonator — shock tolerance and startup
MEMS oscillators typically withstand higher mechanical shock (50,000 g vs 5,000 g for quartz) and start up in under 5 ms — both matter for equipment that sees vibration in transit or on the factory floor.
6-SMD No Lead — layout and sourcing
Housed in a 3.20 mm x 2.50 mm 6-SMD No Lead package with a seated height of 0.90 mm. The 0.50 mm pad pitch and exposed centre pad require a four-layer board for proper LVPECL 50-Ohm controlled-impedance routing and thermal relief.
