ICS85357-11 Description
The ICS85357-11 is a 4:1 or 2:1, Crystal Oscillator-to-3.3V LVPECL / ECL Multiplexer and HiPerClockS™ is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85357-11 has 4 selectable crystal inputs. The device can support 10MHz - 25MHz parallel resonant crystals by connecting external capacitors between XTALIN/XTALOUT and ground.
ICS85357-11 Key Features
- 1 differential 3.3V LVPECL output
- 4:1 or 2:1 Crystal Oscillator Multiplexer
