track-mode response at high input frequencies due to the effect of the output amplifier bandwidth. In particular,
frequencies beyond the output amplifier bandwidth will be attenuated by the transfer function of the output buffer
while the held signal (which looks like DC to the settled output amplifier) will suffer little attenuation.

at high clock rates. However, because of the broad bandwidth, the output amplifier noise contribution to the total
output noise is significant. Users operating at lower clock rates (such as < 1 GHz) may optimize their signal-to-
noise ratio by filtering the output to a lower bandwidth than the output amplifier bandwidth of 7 GHz. Such an
output filter will not reduce the sampled front-end noise (which is frozen into the signal samples and represents
the majority of the T/H noise because of the wide front-end bandwidth) but it can reduce the output amplifier
noise contribution. The user can filter the output to the lowest bandwidth that still retains the maximum settling

clock rate and it can be realized with a simple single pole RC filter if desired. For example, a user operating at
a clock rate of 350 MHz with a 1 GHz noise bandwidth output filter can achieve approximately 2 dB lower noise
relative to the unfiltered output condition.
The output will have very sharp transitions at the clock edges due to the broad output amplifier bandwidth.
The user should be aware that any significant length of cable between the chip output and the load will cause

A common approach to this requirement has been to cascade two T/Hs in a dual rank configuration such that the
second T/H (T/H 2) re-samples the output of the first T/H (T/H 1). The two T/Hs are usually clocked 180 degrees out-
of-phase in master-slave operation to eliminate the track-mode portion of the output waveform from the first T/H. This
arrangement produces an output waveform that consists of two time segments. The first segment is the T/H 1 hold-
