X-REL Semiconductor, a specialist in high reliability and extreme temperature integrated circuits, has broadened its clock and timing product line by introducing a low-power, small foot-print crystal oscillator driver, XTR60010. Intended for operation in high-reliability, extreme temperature and extended lifetime systems, the XTR60010 is tailored for crystal oscillators, clock generation, clock buffering, frequency division and precision timing applications, with supply voltages from 2.5V to 5.5V and with crystals from 32kHz to 50MHz.
Several functional features have been implemented in the XTR60010 to minimize bill-of-material (BoM) and ease adoption, such as automatic gain control of crystal driver, on-chip crystal load capacitors, customer selectable prescaler and programmable frequency divider. This reduction in area and bill-of-material (BoM), together with the ability to adapt to the used crystal without the need for customer intervention, provides a drastic reduction in system complexity, cost and development time, greatly accelerating product qualification cycles and time-to-market.
As with all other X-REL Semiconductor products, the XTR60010 is able to reliably operate well below and above the -60°C to +230°C (5 years at +230°C) temperature range. Being operational at high temperatures is mandatory not only in applications where the environment is at elevated temperature, but also where self-heating of devices within the system increases the temperature inside the application casing. Additionally, all X-REL Semiconductor products can be used in applications running at lower temperatures (e.g. from 100°C to 200°C) where extended lifetime is expected or where failing is not an option. For example, the expected lifetime of X-REL Semiconductor parts in a driver application operating at Tj=150°C is over 35 years.
XTR60010 devices are already available and can be immediately deployed in niche and large-scale markets in high-reliability compact hermetic or plastic packages, as well as bare dies.
