DS32KHZ
32.768kHz Temperature-Compensated Crystal Oscillator
Industry's Most Accurate Temperature-Compensated Crystal Oscillator (TCXO)
Maxim Confidential 
MyMaxim SubscriptionsProduct Details
The DS32kHz is a temperature-compensated crystal oscillator (TCXO) with an output frequency of 32.768kHz. This device addresses applications requiring better timekeeping accuracy, and can be used to drive the X1 input of most Dallas Semiconductor real-time clocks (RTCs), chipsets, and other ICs containing RTCs. This device is available in commercial (DS32kHz) and industrial (DS32kHz-N) temperature versions.
Key Features
- Accurate to ±4 Minutes/Year (-40°C to +85°C)
- Accurate to ±1 Minute/Year (0°C to +40°C)
- Battery Backup for Continuous Timekeeping
- VBAT Operating Voltage: 2.7V to 5.5V with VCC Grounded
- VCC Operating Voltage: 4.5V to 5.5V
- Operating Temperature Range:
- 0°C to +70°C (Commercial)
- -40°C to +85°C (Industrial)
- No Calibration Required
- Low-Power Consumption
- Surface Mountable Using BGA Package
- UL Recognized
Applications/Uses
- Automatic Power Meters
- GPS Receivers
- Network Timing and Synchronization in Servers, Routers, Hubs, and Switches
- Telematics
