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.
