• Available in 8-Pin SOIC or DIE.

DESCRIPTION

The PLL500-27/-37/-47 are a low cost, high perform-

ance, low phase noise, and high linearity VCXO fam-

ily for the 27 to 200MHz range, providing less than -

130dBc at 10kHz offset. The very low jitter (2.5 ps

RMS period jitter) makes these chips ideal for appli-

cations requiring voltage controlled frequency

sources. The IC’s are designed to accept fundamen-

tal resonant mode crystals.
