Denafrips Terra<\/strong> is an MCLK master clock<\/strong> generator intended for high-end audio systems. Its task is to provide a timing reference to the system, using oven-controlled OCXO crystal oscillators<\/strong>. The design integrates dedicated output frequencies and 75-ohm BNC connections, offering a solution specifically intended for audio configurations compatible with an external master clock.<\/p>\n

Terra uses two OCXO crystal oscillators specified for frequencies of 45.1548 MHz and 49.152 MHz. The oscillator oven control is part of the product\u2019s technical configuration and contributes to generating an accurate and stable clock reference. The generated signal can be used, when supported by the connected device, to synchronize audio components equipped with a compatible MCLK input.<\/p>\n

Master clock generator for audio systems<\/h2>\n

In a digital chain, the clock establishes the timing reference used to manage audio data. Denafrips Terra is designed specifically as a dedicated MCLK unit: it is not a DAC, not a streamer and does not perform the functions of an audio source. Its role is to provide clock outputs to devices designed to receive this type of signal.<\/p>\n

The configuration includes both a fixed clock output and an adjustable clock output, as indicated in the product specifications. The value associated with the fixed output is not specified in the available data, while the adjustable output is intended for selecting the compatible frequencies listed for Terra. The availability of adjustable frequencies allows the generator to be configured according to the requirements of the connected system, provided that the latter supports the selected clock connection and format.<\/p>\n

OCXO oscillators and power supply<\/h2>\n

The heart of Denafrips Terra consists of OCXO<\/strong> crystal oscillators, namely oscillators with oven control. The indicated nominal reference frequencies are 45.1548 MHz and 49.152 MHz, with two outputs for each frequency. This architecture is intended to provide a highly accurate and stable clock signal within a compatible audio system.<\/p>\n

The oscillators are powered by a high-current multi-stage linear power supply<\/strong>, combined with an oversized O-Core transformer. The power supply design is therefore an integral part of the Terra solution and supports the clock-generation section. The declared power consumption is equal to or less than 20 W.<\/p>\n

The combination of OCXO oscillators, multi-stage linear power supply and selectable frequencies is intended to generate a stable timing reference. Terra is therefore intended for those who wish to add a dedicated master clock to their audio chain, after first verifying the presence of a compatible input on the component to be synchronized.<\/p>\n

Available output frequencies<\/h2>\n

Denafrips Terra supports several output frequencies, with values associated with the main digital references listed in the specifications. The available options are:<\/p>\n
