Clock oscillators developed for telecommunication applications

29-06-2018 | IQD | Passives

IQD has launched a new range of LVPECL (IQXO-623/IQXO-624) and LVDS (IQXO-618) output clock oscillators with the phase jitter of less than 1ps RMS (over 12kHz to 20MHz) irrespective of which output is specified. Housed in a hermetically sealed 3.2mm x 2.5mm x 1.1mm ceramic six-pad package, the new models are offered in a frequency range from 13.5MHz to 156.25MHz. The devices are principally designed for applications such as Ethernet (10G/40G), Fibre Channel and SONET/SDH. The new oscillators are offered at either 2.5V or 3.3V and with a frequency stability of ±30ppm over an operating temperature range of -40C to 85C. The devices have a maximum current draw of 50mA and rise and fall time of 1ms max and incorporate an enable/disable function on pin 1 as a standard.
