SiTime's programmable, voltage controlled, temperature compensated oscillators (VCTCXO) are the most flexible and reliable solutions for telecom, networking, wireless and embedded applications. They are pin compatible with crystal oscillators and crystal-based TCXO oscillators, enabling 100% drop-in replacement for these crystal-based products with no design or layout changes.
Supported Features of SiTime’s Temperature Compensated Oscillators (TCXO):
- Any frequency within the operating range without any frequency gaps that occur with crystal TCXO oscillators
- Up to 6 decimal places of frequency accuracy, that is just not available from crystal TCXO oscillators and VCTCXOs
- Optional voltage control function, with pull range of ±12.5 PPM to ±50 PPM, provides the ability to fine-tune frequencies after soldering on the board, and increases system performance
- SoftEdge™ programmable drive strength for optimal line impedance matching, better signal integrity and EMI reduction
- Industrial (-40 to +85°C) and commercial temperature (-20 to +70°C) operation
- 1.8V and continuous 2.5-3.3V operation
- 500 million hour MTBF for best-in-class reliability, 10 times better than quartz crystal oscillators and TCXOs
- 50,000 g shock and 70 g vibration immunity, 10 times better than quartz crystal oscillators and TCXOs
- 100% drop in replacement for existing solutions, available in industry standard, 4-pin 3225, 5032 and 7050 packages
