RME keeps steady

RME has rolled out SteadyClock FS, the latest version of its SteadyClock technology that offers synchronisation and jitter suppression in digital audio signals. The femtosecond clock improves self-jitter by improving its second, analogue PLL circuit and referencing both Direct Digital Synthesis and PLL to a low-phase noise quartz crystal.

SteadyClock was originally developed to gain a stable and clean clock from the heavily jittery MADI data signal. Self-jitter is measured through DA conversion and can reach levels that are usually only available in master quartz clock mode. The low phase noise oscillator driving the updated circuit reaches jitter specs lower than a picosecond. SteadyClock FS reportedly features a more efficient filtering and a design based on a super low jitter reference clock.

The first product to include the SteadyClock FS is the ADI-2 DAC converter, which can be used as a USB audio interface, double headphone amplifier, and high-end AD/DA frontend and headphone amp for iOS devices.
