Description

      The ICS840002-01 is a 2 output LVCMOS/LVTTL synthesizer optimized to generate ethernet reference clock frequencies and is a member of the hiperclocks TM family of high performance clock solutions from ICS. using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL1:0): 156.25MHz, 125MHz, and 62.5MHz. The ICS840002-01 uses ICS' 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements. The ICS840002-01 is packaged in a small 16-pin TSSOP package.
      The ICS840002-01 has nine features. The first is two LVCMOS/LVTTL outputs @ 3.3V,17 typical output impedance. The second is selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input. The third is output frequency range, which is 56MHz - 175MHz, the fourth is VCO, which range from 560MHz to 700MHz, the fifth is output skew, which is maximum 12ps. The sixth is RMS phase jitter at 156.25MHZ, which range from 1.875MHz to 20MHz, 0.47ps typically. The seventh is that the ICS840002-01 is full 3.3V or 3.3V core/2.5V output supply mode. The eighth is that the ambient operating temperature range from -30°C to 85°C. The ninth is that the ICS840002-01 available in both standard and lead-free RoHS compliant packages.
      The ICS840002-01 has many absolute maximum ratings. The first is supply voltage, which is 4.6V, the second is inputs, which range 0.5V to + 0.5 V, the third is outputs, which range -0.5V to 0.5V, the third is package thermal impedance, which is 89°C/W (0 lfpm). The last is storage temperature, which range from 65°C to 150°C.
      There are also some notes about absolute maximum ratings of the ICS840002-01. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond those listed in the DC characteristics or AC characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.
