  • Output frequency: 200MHz (typical)
  • Output Skew: TBD
  • Part to Part Skew: TBD
  • RMS phase jitter @ 25MHz output, using a 25MHz crystal (100Hz - 1MHz): 0.16ps (typical) @ VDD = VDDO = 3.3V
  • RMS phase noise at 25MHz: Offset Noise Power
  • Supply Voltage Modes: (Core/Output) 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V
  • 0°C to 70°C ambient operating temperature
  • Industrial temperature available upon request GENERAL DESCRIPTION The ICS83904-02 is a low skew, high perfor- mance 1-to-4 Crystal Oscillator/Crystal-to- LVCMOS Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS83904-02 has selectable single ended clock or two crystal-oscillator inputs. There is an output enable to disable the outputs by placing them into a high-impedance state. Guaranteed output and part-to-part skew characteristics make the ICS83904-02 ideal for those applications demanding well defined performance and repeatability.

Though not required, but for additional protection, a 1kΩ resister can be tied from XTAL_IN to ground. CLK INPUT: For applications not requiring the use of the test clock, it can be left floating. Though not required, but for additional protection, a 1kΩ resister can be tied from the CLK input to ground. TEST CLK INPUT: For applications not requiring the use of the test clock, it can be left floating. Though not required, but for additional protection, a 1kΩ resister can be tied from the TEST_CLK to ground. CLK/nCLK INPUT: For applications not requiring the use of the differential input, both CLK and nCLK can be left floating. Though not required, but for additional protection, a 1kΩ resister can be tied from CLK to ground. PCLK/nPCLK INPUT: For applications not requiring the use of a differential input, both the PCLK and nPCLK pins can be left floating. Though not required, but for additional protection, a 1kΩ resister can be tied from PCLK to ground. SELECT PINS: All select pins have internal pull-ups and pull-downs; additional resistance is not required but can be added for additional protection. A 1kΩ resister can be used. RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS OUTPUTS: LVCMOS OUTPUT: All unused LVCMOS output can be left floating. We recommend that there is no trace attached. LVPECL OUTPUT All unused LVPECL outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated. LVHSTL OUTPUT All unused LVHSTL outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated. LVDS OUTPUT All unused LVDS outputs should be terminated with 100Ω resister between the differential pair. LVDS – Like OUTPUT All unused LVDS outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated. HCSL OUTPUT All unused HCSL outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated. SSTL OUTPUT All unused SSTL outputs can be left floating. We recommend that there is no trace attached. Both sides of the differential output pair should either be left floating or terminated.
