Black Lion Audio MicroClock Mk2

• Output: 3 galvanic-isolated BNC with fixed 75 ohm terminations @ 6 volts peak to peak
• Power: 9-12 volts DC
• Sampling rates: six selectable rates, 44.1 kHz-192 kHz
• Jitter: maximum 1 pico second of intrinsic jitter, less than 10 picoseconds of accumulated jitter measured using a delta sigma averaging method.
• 3 inch by 4 inch chassis that provides optimum RF shielding

It's a solid and stable clock. Highly rated.

Extra awesome because it has three outputs.

I gave it minus one star because I freekin' HATE wall-wart power supplies whose cables are shorter than 6 feet.
