... Philips Semiconductors QIC digital equalizer FUNCTIONAL DESCRIPTION Clock oscillator and divider The clock source for the SZA1000 can be a crystal connected between pins 6 and external clock signal connected to pin 6. This clock frequency is divided by a number programmable between 1 and 8 (see Tables 27 and 28). The resulting frequency, f used as clock input to all on-chip circuits except the write equalizer ...

... Philips Semiconductors QIC digital equalizer Stripe detector This circuit is used to signal the stripes in QIC 3080, QIC 3095 and TR4 servo formats (STRIPE output on pin 21 must be selected; see Table 22). A frequency detector counts the peaks above the qualification threshold (see Table 29). An input signal containing frequencies within 25% of the programmable nominal frequency will be detected as a stripe ...
