INDUSTRY'S FIRST MULTIPORT, T3/E3 ATM/PACKET PHYs WITH BUILT-IN LINE INTERFACE UNITS
DALLAS, TX-March 26, 2004-Dallas Semiconductor (NASDAQ:MXIM) introduces the DS318x family, the industry'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 including the LIU, the DS318x family is a system-on-a-chip solution that minimizes design time, component cost, and board space. The DS3184 is 75% smaller, consumes 32% less power, and costs 33% 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 packets into DS3 or E3 data streams. Direct mapping, PLCP 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 44.736MHz (DS3), 34.368MHz (E3), and/or 51.84MHz 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 design. The ICs are available in a small, high-density, 27mm TE-CSBGA package. All devices are offered in commercial (0°C to +70°C) and extended (-40°C to +85°C) operating ranges. Prices start at $220.00 for the DS3184 and $160.00 for the DS3164 (1000-up, FOB USA). An evaluation kit is available to speed designs. To find additional information on the DS318x family, visit http://www.maxim-ic.com/DS318xPR.
