FEATURES
§ Four E1 (CEPT or PCM-30) /ISDN-PRI
framing transceivers
§ All four framers are fully independent;
transmit and receive sections of each framer
are fully independent
§ Frames to FAS, CAS, CCS, and CRC4
formats
§ 8-bit parallel control port that can be
connected to either multiplexed or non-
multiplexed buses
§ Each of the four framers contains dual two-
frame elastic stores that can connect to
asynchronous or synchronous backplanes up
to 8.192 MHz
§ Easy access to Si and Sa bits
§ Extracts and inserts CAS signaling
§ Large counters for bipolar and code
violations, CRC4 code word errors, FAS
word errors, and E-bits
§ Programmable output clocks for Fractional
E1, per channel loopback, H0 and H12
applications
§ Detects and generates AIS, remote alarm, and
remote multiframe alarms
§ Pin-compatible with DS21Q41B Quad T1
Framer
§ 5V supply; low power CMOS
§ Available in 128-pin TQFP
§ Industrial (-40°C to +85°C) grade version
available (DS21Q43ATN)

DESCRIPTION
The DS21Q43A combines four of the popular DS2143 E1 Controllers onto a single monolithic die. The
“A” designation denotes that some new features are available in the Quad version which were not
available in the single E1 device. The added features in the DS21Q43A are listed in Section 1. The
DS21Q43A offers a substantial space savings to applications that require more than one E1 framer on a
card. The Quad version is only slightly bigger than the single E1 device. All four framers in the
DS21Q43A are totally independent; they do not share a common framing synchronizer. Also, the transmit
and receive sides of each framer are totally independent. The dual two-frame elastic stores contained in
each of the four framers can be independently enabled and disabled as required. The DS21Q43A meets
all of the latest specifications, including CCITT/ITU G.704, G.706, G.962, and I.431 as well as ETS 300
011 and ETS 300 233.
