New TCXO Models Designed For Small Cell Base Stations To Support 5G Architecture

CTS Corporation (announces the release of two new miniature precision TCXO models, 535 and 536, providing a frequency reference with low noise, high stability performance attributes targeted for the evolving 5G New Radio [NR] standard and chipset solutions for small cells and remote radio head applications that will support 5G architecture. The 535 and 536 have been designed to achieve low noise performance at high transmission frequency while remaining energy efficient.

“With the exponential increase in connected devices through the expansion of the IoT coupled with the development of 5G mobile network infrastructures, CTS has developed the 535 and 536 to support our customers in achieving the highest performance,” said Ronen Cohen, senior product manager. “5G network infrastructures promise added capacity, faster data rates and vast improvements in reduced latency. Our new TCXO models will enable applications to operate on the 5G architecture.”

The new CTS models provide a low noise frequency reference signal, tight stability options down to ±0.1ppm, an operating temperature range from -40°C to +105°C that supports outdoor deployment and a choice between Clipped Sine or HCMOS outputs. Optional Voltage Control for frequency tuning and Output Enable function are also available. Standard product features, common market applications and new platforms are summarized below.
