The DS21552LN from Dallas Semiconductor is a versatile T1 single-chip transceiver designed for connection to T1 lines, including DS1 long haul and DSX-1 short haul.
This device integrates complete DS1/ISDN-PRI/J1 transceiver functionality. Key electrical specifications include a supply voltage range of 4.75V to 5.25V and a typical supply current of 75mA. It operates reliably within an ambient temperature range of -40°C to 85°C.
Featuring a crystal-less jitter attenuator and the ability to generate DSX-1 and CSU line build-outs, the DS21552LN ensures signal integrity. It includes an HDLC controller with 64-byte buffers, dual two-frame elastic store slip buffers, and an 8.192MHz clock output locked to RCLK. The interface supports E1, HDLC, J1, and T1 protocols.
The transceiver is housed in a 100-pin LQFP package (14 mm x 14 mm) and is designed for surface mount installation. Its fully independent transmit and receive functionality, along with per-channel loopback capabilities, enhance its utility in telecommunications applications.
