SiT1552
SiT1552 is MEMS TCXO manufactured by SiTime.
Features
- 32.768 k Hz ±5, ±10, ±20 ppm frequency stability options over temp
- World’s smallest TCXO in a 1.5 x 0.8 mm CSP
- Operating temperature ranges:
- 0°C to +70°C
- -40°C to +85°C
- Ultra-low power: <1 µA
- Vdd supply range: 1.5 V to 3.63 V
- Improved stability reduces system power with fewer network timekeeping updates
- Internal filtering eliminates external Vdd bypass cap and saves space
- Pb-free, Ro HS and REACH pliant
Applications
- Smart Meters (AMR)
- Health and Wellness Monitors
- Pulse-per-Second (pps) Timekeeping
- RTC Reference Clock
