The new 2016-sized TCXO belongs to the world's smallest category of packagesEpson Toyocom Corporation has announced the development of a new, smaller, frequency-stable TCXO with frequency stability high enough even for demanding GPS applications. The new oscillator, the TG-5025BA, is housed in a 2016-sized package, putting it in the world's smallest category of packages.
Epson Toyocom is already keeping pace with these GPS market trends with the TG-5005CG, a TCXO equipped with a photo AT chip. However, while the TG-5005CG offers high stability (0.5 x 10-6) in a 2.5 mm x 2.0 mm package, the market is already looking toward even smaller sizes. Epson Toyocom is on target to meet the more stringent size requirements with the commercial development of the TG-5025BA, a 2016-class TCXO that offers outstanding frequency stability despite being in the world's smallest package category.
The TG-5025BA is equipped with a photo AT chip, a very small, crystal chip microfabricated using Epson Toyocom's unique QMEMS technology. In addition to minimal variability of characteristics, the new oscillator promises high reliability thanks to the use of internal wire bonding and Epson Toyocom's original NPO structure. This structure reduces the susceptibility of frequency to changes in ambient temperature. Epson Toyocom's IC design technology brings additional advantages to the TG-5025BA, including precise temperature compensation, low power consumption since driving is performed at voltages as low as 1.68 V, and a wide output frequency range (13-52 MHz).
The TG-5025BA boasts a 36% smaller footprint and a 43% smaller cubic volume than its predecessor (2520 TCXO product). Despite its size, however, it has a frequency-temperature coefficient of 0.5 x 10-6, a rating equivalent to that of a TCXO in a conventional package size. To top it all off, the TG-5025BA is stingy when it comes to power consumption, using some 30% less power than its predecessor.
