Note: *Since the control pins have built-in pull-down resistors (about 70 kΩ), leaving these pins opens effectively sets them to the low level.
Function of the 4FSC Pin
This pin provides a 4fsc clock signal generated by the 4 × PLL frequency multiplier circuit.
Electrical Characteristics at VDD = 5.0 V, Ta = 25°C, FCLK = 3.579545 MHz, VCLK = 500 mVp-p
