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

• XTLOAD signal (reset signal)
• Delay sync output status during hold
The values given in the above table are for when the DSYNC POL register is set to "1". The delay sync
output status is reversed when DSYNC POL is set to "0".
This input pin forces to reset the divider function of the programmable counter.
Since this signal is not normally used, leave it open or fix to high level.
When it is used, this signal is in conjunction with the HOLD signal. See the note given later regarding the
combined use of these signals.
Register: The delay sync output during the hold period can be controlled with the DSYNC Hold register and
the HOLD signal.
The output status resulting from this setting differs based on status of the DSYNC By-pass register.
