The HMC987LP5E 1-to-9 fanout buffer is designed for low noise clock distribution. It is intended to generate relatively square wave outputs with rise/fall times < 100 ps. The low skew and jitter outputs of the HMC987LP5E, combined with its fast rise/fall times, leads to controllable low-noise switching of downstream circuits such as mixers, ADCs/DACs or SERDES devices. The noise floor is particularly important in these applications, when the clocknetwork bandwidth is wide enough to allow squarewave switching. Driven at 2 GHz, outputs of the HMC987LP5E have a noise floor of ?166 dBc/Hz, corresponding to a jitter density of 0.6 asec/rtHz - or 50 fs over an 8 GHz bandwidth.The input stage can be driven single-ended or differentially, in a variety of signal formats (CML, LVDS, LVPECL or CMOS), AC or DC coupled. The input stage also features adjustable input impedance. It has 8 LVPECL outputs, and 1 CML output with adjustable swing/power-level in 3 dB steps.Individual output stages may be enabled or disabled for power-savings when not required using either hardware control pins, or under control of a serial-port interface.APPLICATIONS SONET, Fibre Channel,?GigE Clock Distribution ADC/DAC Clock Distribution Low Skew and Jitter Clock?or Data Fanout Wireless/Wired Communications Level Translation High Performance Instrumentation Medical Imaging Single-Ended to Differential?Conversion

This application report presents the steps necessary to update the bq20z80 firmware and the EVM.

This design is a digitally controlled: bridgeless: 300W: power factor correction (PFC) converter. The distinguishing characteristic of a bridgeless PFC converter is that it eliminates the need for a diode bridge at the input. This reduces power losses that normally occur in a diode bridge and: as a result: improves overall system efficiency. For this design: a C2000™ Piccolo™ TMS320F28035 microcontroller (MCU) is the digital controller for the PFC converter: controlling the two boost power stages that comprise the bridgeless PFC converter. By operating the stages alternatively during the positive and negative half cycles of the AC mains voltage: the Piccolo MCU implements both the AC-to-DC rectification as well as power factor control. This design achieves full load efficiency greater than 93% and power factor of greater than 0.98 at 50% or greater load.
