Specifications

The CY/128 is a bidirectional reed relay multiplexer and is used in general purpose
switching applications. The module is designed with flexibility in mind, and a
variety of different configurations are available. This allows the users to choose
the configuration which most closely matches their requirements. All CYTEC VXI
Modules use both Message and Register based operation.
The CY/128 Multiplexer holds eight individual 8x1 two-
pole multiplexers and four single pole submultiplexer re-
lays. Pin jumpers can be installed to interconnect the
individual multiplexers, allowing the following configu-
rations to be created:
Power +5 Volts less than 1.0 Amp
+12 Volts 20 mA per energized relay
Bandpass (8x1) DC to 80 MHz (-3dB)
Insertion Loss less than 0.2dB at 10 MHz
Isolation/Crosstalk 100 kHz - 80dB
1 MHz - 60dB
10 MHz - 40dB
DC Isolation Greater than10
