Features Closed-loop quad buffer 680MHz small signal bandwidth 3100V/μs slew rate 0.10% / 0.03° differential gain / phase −51dBc THD at 20MHz Single supply operation (3V min.) 80mA output current Description The LMH6560 is a high speed, closed-loop buffer designed for applications requiring the processing of very high frequency signals. While offering a small signal bandwidth of 680MHz, and a very high slew rate of 3100V/μs the LMH6560 consumes only 46mA of quiescent current for all four buffers. Total harmonic distortion into a load of 100Ω at 20MHz is −51dBc. The LMH6560 is configured internally for a loop gain of one. Input resistance is 100kΩ and output resistance is but 1.5Ω. Crosstalk between the buffers is only −55dB. These characteristics make the LMH6560 an ideal choice for the distribution of high frequency signals on printed circuit boards. Differential gain and phase specifications of 0.10% and 0.03° respectively at 3.58MHz make the LMH6560 well suited for the buffering of video signals. The device is fabricated on National's high speed VIP10 process using National's proven high performance circuit architectures. Applications Multi-channel video distribution Video switching and routing High-speed analog multiplexing Channelized EW High-density buffering Active filters Broadcast and high definition TV systems Medical imaging Test equipment and instrumentation
