The LT3825 is an isolated switching regulator controller designed for medium power flyback topologies. A typical application is 10W to 60W with input voltage limited only by external power path components. A third transformer winding provides output voltage feedback.The LT3825 is a current mode controller that regulates output voltage based on sensing secondary voltage via a transformer winding during flyback. This allows for tight output regulation without the use of an opto-isolator, improving dynamic response and reliability. Synchronous rectification increases converter efficiency and improves output cross regulation in multiple output converters.The LT3825 operates in forced continuous conduction mode which improves cross regulation in multiple winding applications. Switching frequency is user programmable and can be externally synchronized. The part also has load compensation, undervoltage lockout and soft-start circuity.Applications Isolated Medium Power (10W to 60W) Supplies Isolated Telecom, Medical Converters Instrumentation Power Supplies Isolated Power over Ethernet Supplies

The HMC6545 is a low power, high performance, fullyprogrammable, dual-channel, asynchronous advanced linear equalizer that operates at data rates of up to 32 Gbps. The HMC6545 is protocol and data rate agnostic, and it can operateon the transmit path to predistort a transmitted signal to invert channel distortion or on the receiver path to equalize the distorted and attenuated received signal. The HMC6545 iseffective in dealing with chromatic and polarization modedispersion and intersymbol interference (ISI) caused by a widevariety of transmission media (backplane or fiber) and channel lengths.The HMC6545 consists of an automatic gain control (AGC);dc offset correction circuitry; a 9-tap, 18 ps spaced feedforward equalizer (FFE); a summing node; and a linear programmableoutput driver. The input AGC linearly attenuates or amplifiesthe distorted input signal to generate a constant voltage at theinput of the FFE. The 9-tap FFE is programmed via 2-wire interface to generate wide range frequency responses that are precursor or postcursor in nature for compensating signal impairments. After FFE tap coefficients are summed at thesumming node, the signal is received by a linear output driver.DC offset correction circuitry is controlled either automatically or manually via Forward Error Correction (FEC).All high speed differential inputs and outputs of the HMC6545 arecurrent mode logic (CML) and terminated on chip with 50 ? tothe positive supply, 3.3 V, and can be dc-coupled or ac-coupled. The inputs and outputs of the HMC6545 can be operated eitherdifferentially or single-ended. The low power, high performance, and feature rich HMC6545 is packaged in a 5 mm ? 5 mm,32-lead LFCSP package. The device uses a single 3.3 V supply,eliminating external regulators.
