Hi,
I am going to use the AD9162 DAC in 11 mm × 11 mm BGA Package (AD9162BBCAZ) in combination with clock distribution device which can provide DC-coupled,
common-mode voltage = 1.03 V SYSREF signal with DIFFERENTIAL SWING = 0.58 V (on 100-ohm differential load).
In the AD9162 datasheet I have not found the electrical specifications for min/max SYSREF DIFFERENTIAL SWING values.
The SYSREF DIFFERENTIAL SWING only mentioned in Table 6: 3 values for device in 8 mm × 8 mm BGA Package and only one value (1.0V) for device in 11 mm × 11 mm BGA Package.
I guess it’s a nominal value.
I want to know which the minimal SYSREF DIFFERENTIAL SWING is. Will the AD9162BBCAZ (in 11 mm × 11 mm BGA Package) work stably with DC-coupled,
common-mode voltage = 1.03 V SYSREF signal with DIFFERENTIAL SWING = 0.58 V ?
I hope it will work on the analogy of device in 8 mm × 8 mm BGA Package, where we can find (in table 6) SYSREF DIFFERENTIAL SWING = [0.4 V; 0.8V; 1.0V].
Regards, Boris.
