Ultra-Small Low Power, Low-Jitter, 1 Hz to 2.5 MHz TCXOLogin
SiTime's TempFlat MEMS™ technology and mixed-signal design expertise enables the first µPower TCXO in a 1.2 mm2 chip-scale package - the world's smallest footprint. Typical core supply current is only 6.0 μA at 100 kHz. And unlike standard oscillators, the SiT1576 Super-TCXO is factory-programmable between 1 Hz and 2.5 MHz. This unique, ultra-small TCXO enables new architectural options with its wide frequency range. The SiT1576 is factory-calibrated over multiple temperature points to guarantee extremely tight frequency stability as low as ±5 ppm (initial and over temperature).
Video Demo: The SiT15xx TCXO is placed in temperature chamber that increases temp. from < -40 to +85 °C at a fast ramp rate of 4 degrees per second.
