EURO
QUARTZ
Stable and clean 100KH differential signals
Uses Inverted MESA, fundamental-mode crystals
No PLL, multiplier or overtone-mode crystals used
Very low jitter <1ps
Miniature 6 pad package, RoHS Compliant
GP576 Series PECL VCXOs
7 x 5 x 2mm SMD Low Jitter PECL VCXO
·
DESCRIPTION
GP
series VCXOs use fundamental mode (inverted mesa) crystal to
achieve wide frequency deviation with stable and clean signals. No
multiplier, overtone crystal or phase lock loop technique is used. As a
result Jitter is as low as for instance 1ps for the 155.520 MHz for
SONET/SDH application. Additionally, the inherent advantages of
differential PECL ECL signal transmission provide improved noise
immunity making the system less susceptible to ground noise.
