TXC launched new product – 2520 Temperature Sensing Crystal (TSX), named OZ TXC Corporation
08/31/2011
TXC’s new Temperature Sensing Crystal “TSX” (crystal with built-in thermistor) in 2520 package size is designed for RF chipsets and combo RF+GPS chipsets used in mobile applications. This TSX product is now available and 3 million pcs and more monthly production capacity has been allocated to customer immediate demand ramp-up.

In the past, crystal and thermistor are soldered on PCB independently. However, different PCB layouts, thermal paths and environment may create different temperature profiles for the crystal and the thermistor.

To date, TXC’s latest technology has proven the ability of “TSX”, a crystal unit with thermistor embedded into one package using “H” type ceramic package structure, has minimized the temperature variations between the crystal and the thermistor. This allows customers to perform easy and accurate frequency adjustment on board in wide operating temperature range. TSX is suitable for all portable devices such as smartphone, tablet, and ultrabook with typical reference synthesizing frequency of 19.2MHz, 26MHz and 38.4MHz.
