DG641, DG642, DG643
Vishay Siliconix
Low On-Resistance Wideband/Video Switches
DESCRIPTION
FEATURES
The DG641, DG642, DG643 are high performance
monolithic video switches designed for switching wide
bandwidth analog and digital signals. DG641 is a quad
SPST, DG642 is a single SPDT, and DG643 is a dual SPDT
function. These devices have exceptionally low
on-resistances (5 typ-DG642), low capacitance and high
current handling capability.

•
•
•
•
Wide bandwidth: 500 MHz
Low crosstalk at 5 MHz: - 85 dB
Low RDS(on): 5 , DG642
TTL logic compatible
Fast switching: tON 50 ns
Single supply compatibility
• High current: 100 mA, DG642
BENEFITS
To achieve TTL compatibility, low channel capacitances and
fast switching times, the DG641, DG642, DG643 are built on
the Vishay Siliconix proprietary D/CMOS process. Each
switch conducts equally well in both directions when on, and
blocks up to 14 Vp-p when off. An epitaxial layer prevents
latchup.

APPLICATIONS
2.
The value of on capacitance [CS(on)] may be reduced.
A property known as ‘the body-effect’ on the DMOS
switch devices causes various parametric effects to
occur. One of these effects is the reduction in CS(on)
for an increasing V body-source. Note however that
to increase V- normally requires V+ to be reduced
(since V+ to V- = 21 V max.). A reduction in V+
causes an increase in rDS(on), hence a compromise
has to be achieved. It is also useful to note that tests
indicate that optimum video linearity performance
(e.g., differential phase and gain) occurs when V- is
around - 3 V.
3.
V- eliminates the need to bias the analog signal using
potential dividers and large coupling capacitors.
Device Description
The DG641, DG642, DG643 switches offer true bidirectional
switching of high frequency analog or digital signals with
minimum signal crosstalk, low insertion loss, and negligible
non-linearity distortion and group delay.
Built on the Siliconix D/CMOS process, these switches
provide excellent off-isolation with a bandwidth of around
500 MHz. The silicon-gate D/CMOS processing also yields
fast switching speeds.
An on-chip regulator circuit maintains TTL input compatibility
over the whole operating supply voltage range shown,
easing control logic interfacing.
Circuit layout is facilitated by the interchangeability of source
and drain terminals.
Frequency Response
A single switch on-channel exhibits both resistance [RDS(on)]
and capacitance [CS(on)]. This RC combination has an
attenuation effect on the analog signal - which is frequency
dependent (like an RC low-pass filter). The - 3 dB bandwidth
of the DG641, DG642, DG643 is typically 500 MHz (into
50 ).
Power Supplies
Power supply flexibility is a useful feature of the DG641,
DG642, DG643 series. It can be operated from a single
positive supply (V+) if required (V- connected to ground).
Decoupling
It is an established rf design practice to incorporate sufficient
bypass capacitors in the circuit to decouple the power
supplies to all active devices in the circuit. The dynamic
performance of the DG641, DG642, DG643 series is
adversely affected by poor decoupling of power supply pins.
Also, of even more significance, since the substrate of the
device is connected to the negative supply, adequate
decoupling of this pin is essential. Suitable decoupling
capacitors are 1- to 10 µF tantalum bead, plus 10- to 100-nF
ceramic or polyester.
Rules:
1.
Note that the analog signal must not exceed V- by more than
- 0.3 V to prevent forward biasing the substrate p-n junction.
The use of a V- supply has a number of advantages:
Decoupling capacitors should be incorporated on all
power supply pins (V+, V-). (see figure 7).
2.
They should be mounted as close as possible to the
device pins.
1.
3.
Capacitors should be of a suitable type with good high
frequency characteristics - tantalum bead and/or
ceramic disc types are adequate.
It allows flexibility in analog signal handling, i.e., with
V- = - 5 V and V+ = 12 V; up to ± 5 V ac signals can
be controlled.

Use extensive ground planes on double sided PCB,
separating adjacent signal paths. Multilayer PCB is
even better.
2.
Keep signal paths as short as practically possible,
with all channel paths of near equal length.
3.
Careful arrangement of ground connections is also
very important. Star connected system grounds
eliminate signal current, flowing through ground path
parasitic resistance, from coupling between
channels.
