The PLL602-35 (LVPECL with inverted OE), PLL602-
37 (LVCMOS), PLL602-38 (LVPECL), and PLL602-39
(LVDS) are high performance and low phase noise XO
IC chips. They provide phase noise performance as
low as –125dBc at 10kHz offset (at 155MHz), by multi-
plying the input crystal frequency up to 32x. The very
low jitter makes them ideal for a wide range of applica-
tions, including SONET/SDH and FEC. They accept
fundamental parallel resonant mode crystals from
12MHz to 25MHz.

On 3x3 package, PLL602-35/-38 do not have SEL0 available: Pin 10
is VDD, pin 11 is GND. However, PLL602-37/-39 have SEL0 (pin
10), and pin11 is VDD. See pin assignment table for details.
