DS32506, DS32508, DS32512
6-/8-/12-Port DS3/E3/STS-1 LIU
Less than 170mW/Port in a Small, 23mm x 23mm BGA
|
Status
Active: In Production.
Description
The DS32506 (6 port), DS32508 (8 port), and DS32512 (12 port) line interface units (LIUs) are highly integrated, low-power, feature-rich LIUs for DS3, E3, and STS-1 applications. Each LIU port in these devices has independent receive and transmit paths, a jitter attenuator, full-featured pattern generator and detector, performance-monitoring counters, and a complete set of loopbacks. An on-chip clock adapter generates all line-rate clocks from a single input clock. Ports are independently software configurable for DS3, E3, and STS-1 and can be individually powered down. Control interface options include 8-bit parallel, SPI™, and hardware mode.
