CD-700, VCXO Based PLL

CD-700 Theory of Operation

Phase Detector

The phase detector has two buffered inputs (DATAIN and CLKIN) which are designed to switch at

1.4 volts. DATAIN is designed to accept an NRZ data stream but may also be used for clock signals

which have a 50% duty cycle. CLKIN is connected to OUT1 or OUT2, or a divided version of one of these

outputs. CLKIN and DATAIN and are protected by ESD diodes and should not exceed the power supply

voltage or ground by more than a few hundred millivolts.

The phase detector is basically a latched flip flop/exclusive-or gate/differential amplifier filter design to

produce a DC signal proportional to the phase between the CLKIN and DATAIN signals (see Figure 4 for

a block diagram and Figure 5 for an open loop transfer curve). This will simplify the PLL design as the

designer does not have to filter narrow pulse signals to a DC level. Under locked conditions the rising

edge of CLKIN will be centered in the middle of the DATAIN signal (see Figure 6).

The phase detector gain is 0.53V/rad x data density for 5volt operation and 0.35V/rad x data density for

3.3 volt operation. Data density is equal to 1.0 for clock signals and is system dependent on coding and

design for NRZ signals, but 0.25 could be used as a starting point for data density.

The phase detector output is a DC signal for DATAIN frequencies greater than 1 MHz but produces

significant ripple when inputs are less than 200 kHz. Additional filtering is required for lower input

frequencies applications such as 8kHz (see Figures 8 and 9 as examples).

Under closed loop conditions the active filter has a blocking capacitor which provides a very high DC

gain, so under normal locked conditions and input frequencies >1 MHz, PHO will be about V

/2 and will

not vary significantly with changes in input frequency (within lock range). The control voltage (pin 16) will

vary according to the input frequency offset, but PHO will remain relatively constant.
