Description

The VT887 is an 3U MTCA.4.1 chassis (RTM backplane does not route all the MTCA.4.1 specification signals) that provides 3 full-size, double-width AMC slots. The chassis backplane is routed on high-speed low loss material for high-speed applications such as 40GbE.

The VT887 has the PinoutPlus™, which allows dual tongue AMC modules to be utilized. The PinoutPlus™ allows more power to each module (up to 200W, only the first two slots) as well as adding an additional 21 pairs of high-speed differential signals between slots. The use of the tongue 2 connector complies with the AMC.0 specification.

The VT887 1100W is universal AC power supply. Two of the slots can dissipate up to 360W each (including the RTM) and the third slot can dissipate up to 90W. The VT887 has an additional power connector on the RTM backplane to allow RTMs to draw up to 160W per slot.

The VT887 has a single MCH slot, Telco Alarm, as well as having an option for the JSM (JTAG Switch Module). It provides FCLKA, TCLKA and TCLKB to each slot.

The Chassis has option to have the RTM in the front or the rear.
