The DS21Q552, a product of DALLAS, is a robust yet compact device that features four completely independent T1 or E1 transceivers all integrated in a tiny 27mm x 27mm package. Each transceiver is packed with features including a short and long-haul line interface, a full-featured framer with alarm detection and generation capabilities, elastic stores for flexible data buffering, hardware-based signaling support, per DS0 channel control, and a HDLC controller. Furthermore, every multi-chip module (MCM) of the DS21Q552 houses four dies including DS21352 (DS21Q352), DS21552 (DS21Q552), DS21354 (DS21Q354), and DS21554 (DS21Q554), offering various configurations based on supply voltage and device type.
DALLAS DS21Q552 Package Dimensions:
A standout feature of the DS21Q552 is its capability to concatenate all four T1 or E1 transceivers into a single 8.192MHz backplane data stream - a testament to its efficiency in data transfer. Adhering to IEEE 1149.1 JTAG-Boundary Scan Architecture, the ODS21Q552 presents pin compatibility between DS21Q352/DS21Q552 and DS21Q354/DS21Q554, allowing the same footprint to comfortably support both T1 and E1 applications. Packaged in a 256-lead MCM BGA (27mm x 27mm) and supporting low-power 5V CMOS or low-power 3.3V CMOS with 5V tolerant inputs & outputs, this product redefines compact power.
