Product Summary
The DS2151Q is a Single-Chip Transceiver (SCT) contains all of the necessary functions for connection to T1 lines whether they be DS-1 long haul or DSX-1 short haul. The clock recovery circuitry automatically adjusts to T1 lines from 0 feet to over 6000 feet in length. The DS2151Q can generate both DSX-1 line build outs as well as CSU build outs of -7.5 dB, -15 dB, and -22.5 dB. The onboard jitter attenuator (selectable to either 32 bits or 128 bits) can be placed in either the transmit or receive data paths.
Parametrics
DS2151Q absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: -1.0V to +7.0V; (2)Operating Temperature: 0°C to 70°C; (3)Storage Temperature: -55°C to +125°C; (4)Soldering Temperature: 260°C for 10 seconds.
Features
DS2151Q features: (1)Complete DS1/ISDN-PRI transceiver functionality; (2)Line interface can handle both long- and short-haul trunks; (3)32-bit or 128-bit jitter attenuator; (4)Generates DSX-1 and CSU line build outs; (5)Frames to D4, ESF, and SLC-96 formats; (6)Dual onboard two-frame elastic store slip buffers that connect to backplanes up to 8.192 MHz; (7)8-bit parallel control port that can be used on either multiplexed or non-multiplexed buses.
