2.3 Timing Recovery and Clock Interface
The timing recovery and clock interface block diagram consists of the timing
recovery circuit and the crystal amplifier, as detailed in Figure 2-5. The main pur-
pose of this circuitry is to recover the clock from the received data. Control fields
include the hclk_freq[1,0] bits of the Serial Monitor Source Select Register
[serial_monitor_source; 0x01], the PLL Modes Register [pll_modes; 0x22], the
Timing
pll_phase_offset_high; 0x24, 0x25] and the PLL Frequency Register
[pll_frequency_low, pll_frequency_high; 0x5E, 0x5F]. See the Register section
of this datasheet for descriptions of these control fields.
