In addition, it provides among the lowest current on the market FIN 3 4 CLK0 for the 10MHz to 52MHz range. The PL600-27T ac- cepts crystal and clock inputs from 10 to 52MHz SOT23-6L (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.
