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

The AD8156, a member of the Xstream line of products, is a high speed, fully differential, digital crosspoint switch. The part can function as a 4 × 4 crosspoint switch with double-latched memory, allowing simultaneous updates, or as a dual 2 × 2 with direct output control. The AD8156 has low power dissipation, typically 700 mW on 3.3 V with all outputs and input equalizers active. It operates at any data rate from dc to 6.25 Gbps per port.Each input channel on the AD8156 has a programmable input equalizer to compensate for signal loss over a backplane.The AD8156 high speed inputs are compatible with both ac-coupled and dc-coupled 3.3 V, 2.5 V, or 1.8 V CML, as well as 3.3 V LVPECL data levels. The control interface is LVTTL- and LVCMOS-compatible at 3.3 V. All input and output termination resistors are integrated for ease of layout and to minimize impedance mismatch. Input equalization and unused outputs can be individually disabled to minimize power dissipation.The AD8156 is packaged in a 49-ball, 8 mm × 8 mm, BGA package with a 1 mm ball pitch. It operates over the industrial temperature range of −40°C to 85°C.APPLICATIONSSONET/SDHGigabit EthernetXAUIFibre Channel

The AD8158 is an asynchronous, protocol-agnostic, quad-lane 2:1 switch with a total of 12 differential CML inputs and 12 differential CML outputs. The signal path supports NRZ signaling with data rates up to 6.5 Gbps per lane. Each lane offers programmable receive equalization, programmable output pre-emphasis, programmable output levels, and loss-of-signal detection.The nonblocking switch-core of the AD8158 implements a 2:1 multiplexer and 1:2 demultiplexer per lane and supports independent lane switching through the four select pins, SEL[3:0]. Each port is a four-lane link. Every lane implements an asynchronous path supporting dc to 6.5 Gbps NRZ data, fully independent of other lanes. The AD8158 has low latency and very low lane-to-lane skew.The main application of the AD8158 is to support redundancy on both the backplane and the line interface sides of a serial link. The demultiplexing path implements unicast and bicast capability, allowing the part to support either 1 + 1 or 1:1 redundancy.The AD8158 is also suited for testing high speed serial links because of its ability to duplicate incoming data. In a port-monitoring application, the AD8158 can maintain link-connectivity with a pass-through connection from Port C to Port A while sending a duplicate copy of the data to test equipment on Port B.The rich feature set of the AD8158 can be controlled either through external toggle pins or by setting on-chip control registers through the I2C interface.ApplicationsLow cost redundancy switchSONET OC48/SDH16 and lower data ratesXAUI/GbE/FC/Infiniband over backplaneOIF CEI 6.25 Gbps over backplaneSerial data-level shift4-/8-/12-lane equalizers or redrivers

The AD818 is a low cost, video op amp optimized for use in video applications which require gains equal to or greater than +2 or -1. The AD818 low differential gain and phase errors, single supply functionality, low power and high output drive make it ideal for cable driving applications such as video cameras and professional video equipment.With video specs like 0.1 dB flatness to 55 MHz and low differential gain and phase errors of 0.01% and 0.05°, along with 50 mA of output current, the AD818 is an excellent choice for any video application. The 130 MHz 3 dB bandwidth (G= +2) and 500 V/µs slew rate make the AD818 useful in many high speed applications including: video monitors, CATV, color copiers, image scanners and fax machines.
