THE FIRST MCH
CONNECTORS FOR MICRO-TCA BY YAMAICHI!
Already a pioneering force for
AdvancedMC connectors, YAMAICHI ELECTRONICS is now also blazing the trail for MCH.
Yamaichi's new CN084 series of MCH connectors offers four different designs that can be
combined to create various different MCH module arrangements. The connectors serve as
adapters between the MicroTCA backplane and the MCH (MicroTCA Carrier Hub) module. The MCH
module functions as the controller card for the AdvancedMC modules and previously carried
the industry designation "Virtual Carrier Manager" (VCM).
To date a total of seven combinations have been realized between backplane and MCH (see
table), thus the design is characterized by a high degree of configuration flexibility.
There are up to four so-called "tongues" on the module side, which are connected
to the backplane via the 170-pin backplane signal connector - also available from Yamaichi
as part of the CN080 series. As a result, the four versions of the CN084 series offer from
170 up to a maximum of 680 contact pins.
Both the backplane and the MCH side are card-edge connections. The CN084 series therefore
enables a reduction of the insertion and extraction forces between the CN080 backplane
connector and the MCH module.

A further significant advantage of using the MCH connector is that it balances the
mechanical tolerances during installation of the MCH module. Undesirable play between
individual MCH modules can be eliminated with the help of the assembly tools, which firmly
fit the module to the connector and thus stabilize it. This ensures a precise and parallel
alignment when installing modules with up to 4 tongues.
Like all connectors conforming to the MicroTCA specification, the CN084 is high-speed
compatible for transmission rates of 12.5Gbps. Beyond this, however, tests have shown that
further potential exists for future applications. Like all Yamaichi products for
high-frequency applications, the high-frequency characteristics of the CN084 are
excellent.
Dedicated, easy-to-use tools that simplify assembly and handling of the CN084 series are
also available.
