FEATURESP
§ 16 or 12 completely independent T1 framers
in one small 27mm x 27mm, 1.27mm pitch
BGA package
§ Each multichip module (MCM) contains
four (FF) or three (FT) DS21Q42 die
§ Each quad framer can be concatenated into a
single 8.192MHz backplane data stream

1. MULTICHIP MODULE DESCRIPTION
The 4 x 4 and 4 x 3 multichip modules (MCM) offer a high-density packaging arrangement for the
DS21Q42 T1 Enhanced Quad Framer. Either three (DS21FT42) or four (DS21FF42) silicon die of these
devices is packaged in an MCM with the electrical connections as shown in Figure 1-1.
All of the functions available on the DS21Q42 are also available in the MCM packaged version.
However, in order to minimize package size, some signals have been deleted or combined. These
differences are detailed in Table 1-1. In the 4 x 3 (FT) version, the fourth quad framer is not populated
and hence all of the signals to and from this fourth framer are absent and should be treated as No
Connects (NC). Table 2-1 lists all of the signals on the MCM and it also lists the absent signals for the
4 x 3.
The availability of both a 12-channel and a 16-channel version allow the maximum framer density with
the lowest cost. For example, in a T3 application, two devices (one DS21FF42 and one DS21FT42)
provide 28 framers without the additional cost and power consumption of any unused framers that appear
in an octal approach.
