Product Summary
The DS2187S is a Receive Line Interface chip interfaces. It user equipment to North American (T1 1.544 MHz) and European (CEPT 2.048 MHz) primary rate communication networks. The DS2187S extracts clock and data from twisted pair or coax transmission media and eliminates expensive discrete components and/or manual tuning required in existing T1 and CEPT line termination electronics. Application areas include DACS, CSU, CPE, channel banks, and PABX-to-computer interfaces such as DMI and CPI.
Parametrics
DS2187S absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: -0.1V to +7.0V; (2)Operating Temperature: 0° to 70°C; (3)Storage Temperature: -55°C to +125°C; (4)Soldering Temperature: 260°C for 10 seconds.
Features
DS2187S features: (1)Line interface for T1 (1.544 MHz)and CEPT (2.048 MHz)primary rate networks; (2)Extracts clock and data from twisted pair or coax; (3)Meets requirements of PUB 43801, TR 62411, and applicable CCITT G.823; (4)Precision on-chip PLL eliminates external crystal or LC tank - no tuning required; (5)Decodes AMI, B8ZS, and HDB3 coded signals; (6)Designed for short loop applications such as terminal equipment to DSX-1; (7)Reports alarm and error events; (8)Compatible with the DS2180A T1/ISDN Primary Rate and DS2181A CEPT Transceivers, as well as DS2141A T1 and DS2143 E1 Controllers.
