MEMS XO
(CMOS)
32.768KHz

• SiTime’s MEMS 32 kHz solutions are ideal for replacing traditional quartz crystals (resonators) in wearable and mobile applications, where space and power are critical.
• Smallest footprint: 1.2 mm2 (1.5 x 0.8 mm) CSP (SiT1532, SiT1572)
• Ultra-low power, as low as <1 μA
• NanoDrive™ programmable output swing minimizes power compared to LVCMOS output (SiT1532/3)
• 1.2V operation-optimized for regulated supply applications, such as coin-cell or super-cap battery backup
• All-inclusive frequency stability, as low as ±50 ppm over temp. (SiT1572)
