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.
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
nonmultiplexed buses
■ Each of the four framers contains dual twoframe 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)
