Micro Crystal offers TCXO in DFN package
The TM-2220-C7 temperature compensated oscillator (TCXO) operates by Micro Crystal operates at 32.768 kHz and has integrated X-Tal and CMOS clock signal output. The temperature compensated frequency reference is designed for applications where reliable and accurate oscillator is needed without frequency jump, says the company.
A high stability over temperature is obtained by integrating a miniature X-Tal resonator coupled to a TCXO ASIC circuit, in closest proximity, explains Micro Crystal.
The compact TCXO measures 3.2 x 1.5 x 0.8mm and has only four connections with 1.5 microA maximum current consumption and frequency stability of ± 5ppm over the full industrial temperature range. The factory calibrated TCXO is embedded in a hermetically sealed, compact, reflow solderable dual flat no leads (DFN) package.
The embedded TM-2220-C7 TCXO achieves significantly better stability performances then separate components on a PCB array, claims Micro Crystal. No oscillator adjustment is required during OEM design phase, for ease of integration and lowering development cost and time to market, according to the company.
TM-2220-C7 TCXO low power module has an operating voltage range of 1.1 to 3.63V and it is designed for high volume and cost sensitive applications where space is constrained and which require stability and extended operation lifetime, for example asynchronous clocking in battery operated devices like IoT, healthcare, wearable devices, metering and automotive.
The part is RoHS-compliant and AEC-Q200-qualified.
