The HMCS46C contains its own oscillator and frequency divider (CPG). The user can obtain the desired timing for operation by merely connecting a resistor Rf or ceramic filter circuit (Internal Clock Operation). Also an external oscillator can supply a clock (External Clock Operation). The maximum Clock Oscillation Frequency is 900 KHz for HMCS46C and 250 KHz for HMCS46CL.
