Dallas Semiconductor Introduces World's First Multiport, T3/E3 ATM/Packet PHYs with Built-in Line Interface Units.Business Editors/High-Tech Writers DALLAS--(BUSINESS WIRE)--March 29, 2004 Dallas Semiconductor (Nasdaq:MXIM) introduced the DS318x family, the world's first multiport DS3/E3 ATM/packet PHYs with fully integrated line interface units (LIUs). The family consists of the DS3184 (quad), DS3183 (triple), DS3182 (dual), and DS3181 (single). By providing a fully integrated DS3/E3 PHY See physical layer and physical. including the LIU LIU Linköpings Universitet (Sweden) LIU Long Island University (New York) LIU Line Interface Unit LIU Lightguide Interconnection Unit (AT&T) LIU Laugh It Up , the DS318x family is a system-on-a-chip solution that minimizes design time, component cost and board space. The DS3184 is 75 percent smaller, consumes 32 percent less power, and costs 33 percent less than existing DS3/E3 solutions. Dallas Semiconductor is also introducing the DS316x family, a line of multiport DS3/E3 ATM/Packet PHYs without LIUs. The family consists of the DS3164 (quad), DS3163 (triple), DS3162 (dual), and DS3161 (single). For added design flexibility, the DS316x family is pin and software compatible with the DS318x family. All ports of the DS318x and DS316x families are independently configurable for DS3, E3, or external framing protocols up to 52 Mbps. The universal PHYs map ATM cells and/or HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. packets into DS3 or E3 data streams. Direct mapping, PLCP PLCP Physical Layer Convergence Procedure (SONET) PLCP Planning Command Pool PLCP Physical Layer Conversion Protocol (DQDB, NEC) PLCP Premobilization Legal Counseling Program and clear-channel cell mapping, and direct and clear-channel packet mapping are supported. The devices also support subrate (or fractional) DS3/E3 with internal circuitry and special external interfaces. System interface options include UTOPIA 2/3 and POS-PHY 2/3 with 8-, 16- or 32-bit bus width up to 66 MHz. The ports are independently configurable for cell or packet traffic in POS-PHY bus modes. The DS318x and DS316x devices also feature an integrated clock-rate adapter to generate the required 44.736 MHz (DS3), 34.368 MHz (E3), and/or 51.84 MHz from a single DS3, E3, or STS-1 input clock frequency. Each port can be disabled to reduce power. All eight DS318x and DS316x devices are pin and software compatible for easy port-density migration on a single PCB PCB: see polychlorinated biphenyl.

The ICs are available in a small, high-density, 27mm TE-CSBGA package. All devices are offered in commercial (0 degrees Celsius to +70 degrees Celsius) and extended (-40 degrees Celsius to +85 degrees Celsius) operating ranges. Prices start at $220 for the DS3184 and $160 for the DS3164 (1000-up, FOB USA). An evaluation kit is available to speed designs.
