DESCRIPTION

The PL600-27T is a low cost XO IC, designed to re-

place multiple XO solutions saving the cost and

board space of clock distribution buffers. In addition,

it provides among the lowest current on the market

for the 10MHz to 52MHz range. The PL600-27T ac-

cepts crystal and clock inputs from 10 to 52MHz

(fundamental resonant mode crystal) and provides

low phase noise (<-130dBc at 10kHz offset at

30MHz), and very low jitter (2.5 ps RMS period jitter)

outputs.

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the

device and affect product reliability. These conditions represent a stress rating only, and functional operations of the dev ice at these or any other

conditions above the operational limits noted in this specification is not implied. *Operating t emperature is guaranteed by design. Parts are

tested to commercial grade only.
