SiT8503: High Performance 200kHz - 1000kHz Programmable Oscillator

E-mail Print

The SiT8503 is the industry’s first programmable oscillator optimized for kHz applications. It comes in four standard packages to enable drop-in replacement of quartz without PCB re-design.

 

 

Frequency Range (kHz) 200 – 1000 (Contact SiTime for frequencies less than 200 kHz)
Frequency Stability (PPM) ±20, ±25, ±30, ±50
Temp Range (°C) -20 to +70, -40 to +85
Supply Voltage (V) 1.8, 2.5, 2.8, 3.3
Package LxWxH (mm) 2.5x2.0x0.75, 3.2x2.5x0.75, 5.0x3.2x0.75, 7.0x5.0x0.9
