4. Contact factory for other power supply operating voltage ranges, including Vsupply = ±3V or Vsupply = ±2.5V.
5. Recommended selection of clock periods of one of the following:
t clk = 0.27µsec, 0.54µsec, or 1.09µsec
which corresponds to clock frequencies of 3.6864 MHz, 1.8432 MHz, 0.9216 MHz respectively.
