Description
AI
The AD8152 is a breakthrough cross point switch offering a large switch array (34 × 34) on very little power, typically 2.0 W. Additionally, the device operates at data rates up to 3.2 Gbps per port, making it suitable for Sonet/SDH OC-48 with forward error correction (FEC).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.The fully differential signal path of the AD8152 reduces jitter and crosstalk and allows the use of smaller single-ended voltage swings. The device is offered in a 256-ball BGA_ED package that operates over the industrial temperature range of 0°C to 85°C.ApplicationsFiber optic network switchingHigh speed serial backplane routing to OC-48 with FECGigabit ethernetDigital video (HDTV)Data storage networks
