IQD’s new analogue ASIC-based temperature-compensated crystal oscillator (TCXO) is tested using one frequency reading every two degrees centigrade over the full operating temperature range. “This, combined with a high order compensation circuit, delivers a frequency stability as tight as ±0.5ppm over -40 to +85°C,” said the firm. Called IQXT-274, it comes in a 3.2 x …
