C9837
Low EMI Clock Generator for Intel Mobile 133MHz/2 SO-DIMM Chipset Systems
Preliminary
Maximum Ratings
This device contains circuitry that protects the inputs
against damage due to high static voltages or electric
field; however, precautions should be taken to avoid
application of any voltage higher than the maximum
rated voltages to this circuit. For proper operation, Vin
and Vout should be constrained to the range:
Maximum Input Voltage Relative to VSS: VSS - 0.3V
Maximum Input Voltage Relative to VDD: VDD + 0.3V
Storage Temperature:
Operating Temperature:
Maximum ESD Protection
Maximum Power Supply:
-65°C to + 150°C
0°C to +70°C
2KV
VSS<(Vin or Vout)<VDD
5.5V
Unused inputs must always be tied to an appropriate
logic voltage level (either VSS or VDD).
