That means it replaces a multi-chip solution: a line interface unit plus a separate HDLC controller, saving board area and reducing the BOM count on telecom line cards, access multiplexers, and CPE equipment. ## Supply rail tolerance and what it means for the regulator The supply range is 3.14 V to 3.47 V — a tight 330 mV window centred on 3.3 V. A standard 3.3 V LDO with ±2% tolerance (3.23 V to 3.37 V) stays inside the band, but a buck converter with 50 mV ripple needs the output set point above 3.19 V to keep the troughs above the 3.14 V floor. Drawing 75 mA typical, the transceiver's own dissipation in the 100-LQFP package is under 260 mW — no forced airflow needed in a ventilated enclosure, but the thermal pad on the 14x14 mm body should get a via-stitched copper pour on the PCB. ## Temperature grade and deployment environment This covers outdoor cabinets, unheated comms shelters, and the inside of a roadside access multiplexer where the internal air temperature can hit 70°C on a summer day. ## Package and rework bench reality 100-LQFP, 14x14 mm body, 0.5 mm pitch — a standard fine-pitch QFP that any rework station with a bottom preheater and a hot-air nozzle can remove and replace. The exposed pad on the bottom centre needs a stencil aperture for the thermal via array; without it the centre joint voids and the thermal resistance climbs. Supplied in tray format — not tape-and-reel, so pick-and-place feeders need a tray feeder or a tube adapter. For a repair bench pulling one-off replacements, the tray is actually easier: no tape to cut, no reel to store.","metaTitle":"Analog Devices DS21354LN+ E1 Single-Chip Transceiver","metaDescription":"DS21354LN+ active E1/HDLC transceiver, 3.14V–3.47V supply, -40°C to +85°C, 100-LQFP.
