T C X O – Ultra Low Current “M57K” SERIES 5x7 mm Logic: HCMOS Wave Form: Square Wave MERCURY Since 1973 With M57K design engineers enjoy the benefits of HCMOS output, TCXO stability, ultra low current and miniaturized 5x7 packaging. M57K consumes less than 4 mA at 26 MHz +3.3 V with low phase noise of -130 dBc / Hz at 1 KHz offset. M57K also features Tri-state option on pad 1. Oscillator can be tuned off by grounding the pad 1 to further reduce the power.
