com Description
The NB3N3011 is a Fibre Channel Clock Generator and uses a 26.
5625 MHz crystal to synthesize 106.
25 MHz or a 25 MHz crystal to synthesize 100 MHz.
The NB3N3011 has excellent <1 ps phase jitter performance over the 637 kHz – 10 MHz integration range.
The NB3N3011 is packaged in an 8−Pin 4.
4 mm x 3.
0 mm TSSOP, making it ideal for use in systems with limited board space.
