... Additional considerations using the PWM for 10-bit Data The 14.3 MHz CLK1 clock rate of the RSC-4128 is not fast enough to provide PWM synchronization with 10-bit 8kHz or 9.3 kHz data. To understand this, consider a PWM rate of 8 kHZ (125 microsec). To output 10 bits (9 bits plus sign) during this interval, a source must provide 512 clocks, giving a source rate of 125000/512 = 244 nsec ...
