Manufacturer:TI Description:DATA SEPARATOR The internal data separator consists of an analog PLL and its associated circuitry The PLL synchronizes the raw data signal read from the disk drive The synchronized signal is used to separate the encoded clock and data pulses The data pulses are de-serialized into bytes and then sent to the mP by the controller The main PLL consists of four main components a phase comparator a filter a voltage controlled oscillator (VCO) and a programmable divider The phase comparator detects the difference between the phase of the dividers output and the phase of the raw data being read from the disk This phase difference is converted to a current which either charges or discharges one of the three external filters The resulting voltage on the filter changes the frequency of the VCO and the divider output to reduce the phase difference between the input data and the dividers output The PLL is locked when the frequency of the divider is exactly the same as the average frequency of the data read from the disk A block diagram of the data separator is shown in Fig- ure 3 |
