Transpar Descriptions
and Applications <
back to Centaur Modular Interface
The Transpar Signal Modules used in the Centaur Modular
Interface give you significant connection flexibility.
They are available in a variety of standard configurations:
 |
 |
Transpar A module
with 146 pins. |

|
 Type
A: Coaxial Airline (part number 46-64295).
The Type A Module is populated with 80 high-speed coaxial airline
signal paths with associated ground pins. This module type is ideal
for high-performance digital and analog signal transmission where
a controlled 50-ohm transmission line is required (for example, with
parallel synchronous signals), or where high isolation between lines
is required (for example, in a communications chip that has I and
Q signals). |

 |
|
Transpar C module
with 160 pins.. |

Type
C: Coplanar Ground (part number 46-64401).
The Type C Module uses a parallel-wire transmission line. The parallel-wire
method allows the user to define controlled impedance paths. It is
ideal for analog signal transmission (i.e., differential pairs, or
balanced/unbalanced lines) or low bandwidth digital signals. This
module is also well-suited to bringing power supplies and sense lines
to the probe card. |

module with 162 pins. |

|
|
Type
A/U: Coaxial Airline with Utilities
(part number 46-64469).
The type A/U Signal Module is a high-speed coaxial airline design
with an additional 32 utility pins. The module is populated with 65
high-speed coaxial airline signal paths with associated ground pins,
and 32 utility pins that electrically float in the segment.
The A/U Module is ideal for high-performance digital and analog signal
transmission where a controlled 50-ohm transmission line is required
(for example, with parallel synchronous signals), or when high isolation
between lines is required; for example, in a communications chip that
has I and Q signals. The utility pins can be used for relay control
lines, power supplies or any other generic pin type. |

Type
C/U: Coplanar Ground with Utilities
(part number 46-64486).
The Coplanar Ground with Utilities Module is based on the same layout
pattern as the Coaxial Airline with Utilities Module (Type A/U: 46-64294).
The Type C/U Module uses a parallel-wire transmission line. The parallel-wire
method allows the user to define controlled impedance paths. It is
ideal for analog signal transmission (i.e., differential pairs, or
balanced/unbalanced lines) or low bandwidth digital signals. This
module is also well-suited to bringing power supplies and sense lines
to the probe card. |
Type
D Load-Balancing Module (part number 46-64430).
The 46-64430 is an electrically inactive load-balancing module. If a signal
module is not installed (in one of the available signal module births in
the Centaur Modular Interface), then this load-balancing module is installed
in its place to assure that compression loads are distributed evenly.
