Zarlink (Zarlink Semiconductor ) : MT90225

16 Port TC PHY Device

The MT90225/226 family, are multi-rate transmission convergence (TC) or UNI (User Network Interface) devices that process ATM traffic for transmission over T1/E1, fractional T1/E1 and DSL lines. The MT90225/226 integrates features that optimize flexibility and easy implementation of broadband access equipment. The MT90225/226 is a single chip ATM TC processor and supports up to 16 independent links. The MT90225/226 can be configured to operate in different TDM modes to facilitate the implementation of ATM over T1/E1/DSL at both CPE and Central Office sites. The MT90225/226 and MT90222/223/224 share the same product package and pinout configuration and the MT90225/226 is compliant with the ATM Forum TC/UNI specifications for T1/E1 rates.
