FEATURES
3 CMOS outputs with OE tri-state control
Low current consumption:
PLL600-27T: <4.5mA @ 27MHz with standard
CMOS buffer (3.3V)
PLL600-37T: <3.0mA @ 27MHz with CMOS
compatible Clipped buffer, offering
the lowest current consumption
(3.3V)
10 to 52MHz fundamental crystal input.
Low phase noise (-130 dBc @ 10kHz offset).
Low jitter (RMS): 2.5ps period jitter.
12mA drive capability at TTL output.
1.62V to 3.63V DC operation.
Available in 8 pin SOIC.
DESCRIPTION
The PLL600-27T/-37T form a low cost family of XO
IC's, designed to replace multiple XO solutions sav-
ing the cost and board space of clock distribution
buffers. In addition, they provide among the lowest
current on the market for the 10MHz to 52MHz
range. They accept input crystals from 10 to 52MHz
(fundamental resonant mode) and provide low phase
noise (<-130dBc at 10kHz offset at 30MHz), and very
low jitter (2.5 ps RMS period jitter) outputs.
