Fiber optic network switching High speed serial backplane routing to OC-48 with FEC Gigabit ethernet Digital video (HDTV) Data storage networks GENERAL DESCRIPTION The AD8152 is a breakthrough cross point switch offering a The fully differential signal path of the AD8152 reduces jitter large switch array (34 34) on very little power, typically 2.0 W. and crosstalk and allows the use of smaller single-ended voltage Additionally, the device operates at data rates up to 3.2 Gbps per swings. The device is offered in a 256-ball BGA ED package port, making it suitable for Sonet/SDH OC-48 with forward that operates over the industrial temperature range of 0C to error correction (FEC). 85C. The useful supply voltage range of the AD8152 allows the user to operate at LVPECL/CML data levels down to 2.5 V. The control interface is low voltage transistor transistor logic (LVTTL) or low voltage complementary metal-oxide (LVCMOS) compatible on 2.5 V to 3.3 V. Rev.
