The ECOC-9775-10.000-DN-TR is a 10.000 MHz Oven Controlled Crystal Oscillator (OCXO) that provides a highly stable frequency reference. This oscillator operates on a nominal +3.3 VDC supply and provides an LVCMOS output, featuring a tight frequency stability of ±20 ppb over a wide operating temperature range of -40°C to +85°C. The device exhibits excellent phase noise performance, with a typical value of -162 dBc/Hz at a 10 kHz offset. Housed in a compact 9.7 x 7.5 mm surface-mount package, it is ideal for demanding applications such as 5G infrastructure, small cells, Synchronous Ethernet (SyncE), and IEEE 1588 timing protocols.
