Multiport PHYs Integrate Line Interface Units

Consisting of the DS3184 (quad), DS3183 (triple), DS3182 (dual), and DS3181 (single), the DS318x family takes a bow as the industry's first multi-port DS3/E3 ATM/packet PHYs with fully integrated line interface units (LIUs). All ports on each device are independently configurable for DS3, E3, or external framing protocols up to 52 Mb/s. They map ATM cells and/or HDLC packets into DS3 or E3 data streams with support for direct mapping, PLCP and clear-channel cell, and direct and clear-channel packet mapping. 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 widths up to 66 MHz. Available in 27-mm TE-CSBGA packages, prices for the DS3184 and DS3164 start at $220 and $160 each/1,000, respectively. DALLAS SEMICONDUCTOR, Dallas, TX. (800) 998-8800.
