Timer integrated circuit
Hittite Microwave
The data inputs to the HMC856LC5 are terminated onchip with 50-Ohms to the positive supply, GND, and may be DC or AC coupled. The differential outputs are source terminated to 50-Ohms and may be AC or DC coupled. The control lines B4:B0 are differential CML inputs terminated with 600 Ohms to the positive rail, which supports lower power control options. The HMC856LC5 features an output level control pin, VR, which allows for loss compensation or signal level optimization. The HMC856LC5 operates from a single -3.3V supply and is available in ROHS compliant 5x5 mm SMT package.
