NB3N3011
3.3 V 100 MHz / 106.25 MHz
PureEdge Clock Generator
with LVPECL Differential
Output
Description
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.
