Si549 Datasheet and Specifications PDF

Selectable via ordering option OE = Output enable; FS = Frequency Select; NC = No connect GND = Ground CLK+ = Clock output CLK- = Complementary clock output. Not used for CMOS. VDD = Power supply SDA.

* I2C programmable to any frequency from 0.2 to 1500 MHz with < 1 ppb resolution
* Ultra low jitter: 95 fs Typ RMS (12 kHz
* 20 MHz)
* Configure up to 4 pin-selectable startup frequencies
* I2C interface supports 100 kbps, 400 kbps, and 1 Mbps (Fast Mode Plus)
* Excellent PSNR and supply noise immun.
