Differential Clock Translation - Microchip Technology
ww1.microchip.comA typical HCSL driver is a differential logic with open-source outputs, where each of the pins switches output between 0 and 14mA. When one output pin is low (0), the other is high (driving 14mA). The output pins of OUT+ and OUT− are typically connecting to differential transmission lines (Z 0 = 100Ω) or a single-ended transmission line (Z 0
Clock Tree 101 - Mouser Electronics
www.mouser.comClock buffers are fairly straight-forward ICs for distributing multiple copies of a clock to multiple ICs with the same frequency requirements. A buffer’s reference clock can be from a clock generator, an XO or a clock already present. Clock buffers scale from 2 …
