FEATURESP
Sixteen (16) or twelve (12) completely
independent T1 Framers in one small 27 mm
x 27 mm, 1.27 mm pitch BGA package
Each Multi-Chip Module (MCM) contains
four (FF) or three (FT) DS21Q42 die.
Each Quad Framer can be concatenated into
a Single 8.192 MHz Backplane Data Stream
IEEE 1149.1 JTAG-Boundary Scan
Architecture
DS21FF42 and DS21FT42 are pin
compatible with DS21FF44 and DS21FT44,
respectively, to allow the same footprint to
support T1 and E1 applications
300–pin MCM 1.27 mm pitch BGA package
(27 mm X 27 mm)
Low power 3.3V CMOS with 5V tolerant
input & outputs
1. MULTI-CHIP MODULE (MCM) DESCRIPTION
The Four x Four and Four x Three MCMs 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 a Multi-Chip Module (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 Four x Three (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 Four x Three.
The availability of both a twelve and a sixteen-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 a total of 28 framers without the additional cost and power consumption of any unused framers
that appear in an octal approach.
