T C X O – Ultra Low Current
“M57K” SERIES 5x7 mm
Logic: HCMOS
Wave Form: Square Wave
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.
