APPLICATIONS
Device Description
The DG534A/538A D/CMOS wideband multiplexers offer
single-ended or differential functions. A 8/4 or 4/2 logic input
pin selects the single-ended or differential mode.
To meet the high dynamic performance demands of video,
high definition TV, digital data routing (in excess of 100 Mbps),
etc., the DG534A/538A are fabricated with DMOS transistors
configured in ‘T’ arrangements with second level ‘L’
configurations (see Functional Block Diagram).
Use of DMOS technology yields devices with very low
capacitance and low rDS(on). This directly relates to improved
high frequency signal handling and higher switching speeds,
while maintaining low insertion loss figures. The ‘T’ and ‘L’
switch configurations further improve dynamic performance
by greatly reducing crosstalk and output node capacitances.
The
DG534A/DG538A
are
improved
pin-compatible
replacements for the non-A versions. Improvements include:
higher current readback drivers, readback of the EN bit,
latchup protection
Frequency Response
A single multiplexer on-channel exhibits both resistance
[rDS(on)] and capacitance [CS(on)].
This RC combination
causes a frequency dependent attenuation of the analog
signal. The –3-dB bandwidth of the DG534A/538A is typically
500 MHz (into 50
W). This figure of 500 MHz illustrates that the
switch-channel cannot be represented by a simple RC
combination. The on capacitance of the channel is distributed
along the on-resistance, and hence becomes a more complex
multi-stage network of R’s and C’s making up the total rDS(on)
and CS(on).
