• Manufacturer Part Number: cxa3516r
• Description: 3-channel 8-bit 165msps A/d Converter Amplifier Pll
• Manufacturer: Sony Electronics

• Delay time setting (Fine Delay/Coarse Delay)
• DIVOUT signal output pulse width
• DIVOUT signal output delay time setting
• Delay sync output polarity
• Delay sync output status
The delay sync output, clock output, and 1/2 clock output can make delay time setting (Fine Delay/Coarse
Delay) for the input signal. The amount of delay time is from 3CLK Delay to 6CLK Delay for Coarse Delay
and from 1/32CLK to 64/32CLK for Fine Delay.
The delay time (Fine Delay/Coarse Delay) can be set by using the control registers shown below.
The pulse width of the DIVOUT signal output can be set to 1, 2, 4, 8 clock pulse widths by using a control
register.
The DIVOUT signal is output with 4 or 5 clock delay based on the delay time (Fine Delay/ Coarse Delay)
set as described above.
The clock delay time can be set by using a control register.
The polarity of the delay sync signal output from the DSYNC/DIVOUT pin can be selected either negative or
positive by using a control register.
Although it is possible to turn off the signal output from the DSYNC/DIVOUT pin by using a control register,
it cannot be set to high impedance.
