Analogue inputs
AC coupled option. 2.4 Vp-p (11.5 dbm –50 Ohm) Full scale - AC
coupled via RF transformer. DC coupled option. 1.15 Vp-p (Gain
amplifier 6dB) centered around 0. DC coupled via amplifier. Gain
can be adjusted to a required input amplitude centered around 0.
Minimm gain 6dBs, which should allow input swing +/-0.575V as
full scale.
ADC single-ended inputs are to be connected to a 50Ù source.
Source impedance matching implemented between RF transformers
and ADC.
ADC bandwidth: 750 MHz.
External Reference input
0.5 – 3.3 Volts peak-to-peak (AC-coupled)
50-Ohm (Termination implemented at the connector)
0-100MHz
External Reference output
