Silent Angel Bonn NX Ethernet Switch and Genesis GX Word Clock Review
Compared with “stand-alone” word clocks, built-in word clocks share system resources (e.g., power supplies, etc.) with other device components, and are all interconnected on the same circuit board. By contrast, stand-alone word clocks are less susceptible to noise components that can affect the clock signal, such as electrical pulses, interference from other electronic components, and noise from jitter caused by other system components, and thus, provide a more accurate clock signal. A key point and benefit of the Genesis GX is that it can be used with all digital components that have a Word Clock input, e.g., a DAC, streamer, or network bridge, and is not limited to use with Silent Angel’s or other manufacturer’s Ethernet switches.
The Genesis GX has four individual word clocks: two 10 MHz and two 25 MHz units. While 10MHz is the most commonly used frequency for word clocks, this frequency was initially chosen for GPS applications and Silent Angel claims this frequency is not optimal for audio applications. After exhaustive testing, Silent Angel’s R&D team discovered that the ideal frequency for audio networking devices is 25MHz. The Genesis GX features both 10MHz and 25MHz clock outputs for use with Silent Angel products, such as the Bonn NX Ethernet switch, as well as providing compatibility with other Ethernet switches. Using four discrete word clocks in a single optimized enclosure provides flexibility for networking audio configurations, as the increased performance Silent Angel claims is obtainable from the 25 MHz clock rate. The clock units are spaced and electrically isolated to minimize interference and noise. Each clock unit has its own temperature-controlled crystal oscillator clock (TCXO) clock and circuitry to eliminate potential signal interference.
