Dallas Semiconductor
Dallas Semiconductor, acquired by Maxim Integrated in 2002 for $2.5 billion,then acquired by Analog Devices in 2021, was a company that designed and manufactured analog, digital, and mixed-signal semiconductors (integrated circuits, or ICs). Its specialties included communications products (including T/E and Ethernet products), microcontrollers, battery management, thermal sensing and thermal management, non-volatile random-access memory, microprocessor supervisors, delay lines, silicon oscillators, digital potentiometers, real-time clocks, temperature-compensated crystal oscillators (TCXOs), iButton, and 1-Wire products.

The DS2187S T1/CEPT Receive Line Interface chip interfaces user equipment to North American (T1 1.544 MHz) and European (CEPT 2.048 MHz) primary rate communication networks. The device 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.
FEATURES
Line interface for T1 (1.544 MHz) and CEPT (2.048 MHz) primary rate networks
Extracts clock and data from twisted pair or coax
Meets requirements of PUB 43801, TR 62411, and applicable CCITT G.823
Precision on-chip PLL eliminates external crystal or LC tank - no tuning required
Decodes AMI, B8ZS, and HDB3 coded signals
Designed for short loop applications such as terminal equipment to DSX-1
Reports alarm and error events
Compatible with the DS2180A T1/ISDN Primary Rate and DS2181A CEPT Transceivers, as well as DS2141A T1 and DS2143 E1 Controllers
Companion to the DS2186 T1/CEPT Transmit Line Interface and DS2188 T1/CEPT Jitter Attenuator
Single 5V supply; low-power CMOS technology
