The ADN3000 is a complete high-speed optical receiver featuring a proprietary large-area germanium PIN photodiode integrated with a transimpedance amplifier (TIA). The integration of the photodiode eliminates bond wires between the detector and TIA that provides guaranteed performance and improved manufacturing reliability. The part supports data rates of up to 11 Gb/s and a wide range of operating wavelengths from 850 nm to 1550 nm.The ADN3000 also features an average power loop and an on-chip power monitor circuit that generates a voltage proportional to the average photodiode current. Typical power consumption is 65 mW from a single 3.3 V supply. In saturated output, the signal has a typical differential amplitude of 270 mV p-p (240 mV p-p for ADN3000-06).The ADN3000 is available in die form, and is rated for operation over the extended industrial temperature range of -40°C to +85°C.ApplicationsADN3000-06Optical receivers up to 6 Gb/s6G CPRI, OBSAI, and LTE receiversReceiver optical subassemblies (ROSA)ADN3000-11Ethernet, Sonet/SDH and Fiber Channel receivers up to 11 Gb/sReceiver optical subassemblies (ROSA)

The ADN4600 is an asynchronous, nonblocking crosspoint switch with eight differential PECL-/CML-compatible inputs with programmable equalization and eight differential CML outputs with programmable output levels and pre-emphasis or de-emphasis. The operation of this device is optimized for NRZ data at rates up to 4.25 Gbps.The receive inputs provide programmable equalization with nine settings to compensate for up to 30 in. of FR4 and programmable pre-emphasis with seven settings to compensate for up to 30 in. of FR4 at 4.25 Gbps.The ADN4600 nonblocking switch core implements an 8 × 8 crossbar and supports independent channel switching through the I2C control interface. Every channel implements an asynchronous path supporting NRZ data rates from dc to 4.25 Gbps. Each channel is fully independent of other channels. The ADN4600 has low latency and very low channel-to-channel skew.The main application for the ADN4600 is to support switching on the backplane, line card, or cable interface sides of serial links.The ADN4600 is packaged in a 9 mm × 9 mm, 64-lead LFCSP package and operates from −40°C to +85°C.APPLICATIONS1×, 2×, 4× FibreChannelXAUIGigabit Ethernet over backplane10GBase-CX4InfiniBand®50 Ω cables

The ADN4620/ADN4621are dual-channel, signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 2.5 Gbps with very low jitter. The devices integrate Analog Devices, Inc.,iCoupler®technology, enhanced for high speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows isolation of other high speed signals, such as current mode logic (CML).The ADN4620/ADN4621 include a refresh mechanism to monitor the input and output states and ensure that they remain the same in the absence of data transitions (for example, at power-on). For lower power consumption and high speed operation with low jitter, the isolator circuits rely on 1.8 V supplies, while 3.3 V supplies are used for LVDS receivers to support the full common-mode range with an input voltage range (input common mode plus differential input voltage) of 0 V to 2.4 V per Table 2 in the data sheet.The devices are fully specified over a wide industrial temperature range and are available in a compact SSOP package with 5.3 mm creepage (for reinforced insulation at ac mains voltages) or a wide SOIC_IC package with 15.1 mm creepage (for high working insulation voltages up to 1500 V peak, reinforced).APPLICATIONSAnalog front-end isolationData plane isolationIsolated high speed clock and data linksMultigigabit serialization/deserialization (SERDES)PCB-to-PCB optical replacement (for example, short reach fiber)Protected by U.S. Patents 7,075,329; 9,941,565; and 10,205,442.
