IC for XO
Monolithic IC MM1424, MM1624 Series
Outline
This is a low current consumption, low operating voltage XO IC with Colpitz oscillation circuit. Smaller size is
achieved by the on-chip bias circuit and Colpitz oscillation capacitor.
Features
1. Low current consumption.
1.5mA max. (Vcc = 2.8V)
Vcc = 2.3 to 3.3V
2. Low power supply operating voltage.
3. On-chip Colpitz oscillation capacitor · On-chip bias resistor.
4. Low phase noise.
-140dBc (@1kHz)
5. Ultra-small package type.
Package
