Zarlink (Zarlink Semiconductor ) : ZL30227

8 port IMA & TC PHY for xDSL

The ZL30226/227/228 family are multi-rate inverse multiplexing for ATM (IMA) and transmission convergence (TC) devices that process ATM traffic for transmission over xDSL lines. The ZL30226/227/228 integrates features that optimize flexibility and easy implementation of broadband access equipment. A mixed-mode configuration allows links not assigned to an IMA group be used in TC mode. The ZL30226/227/228 can be configured to operate in different modes to facilitate the implementation of the IMA function at both CPE and Central Office sites. The ZL30226/227/228 can also be interfaced with major vendor chip sets that implement G.SHDSL to apply IMA over SHDSL lines. The ZL30226/227/228 devices are compliant with ATM Forum IMA specifications (Versions 1.1, 1.0 & UNI) for controlling IMA groups of up to 16 trunks on a single chip.
