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.
