They provide phase noise performance as low as –127dBc at 10kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x. The very low jitter makes them ideal for a wide range of applications, including SONET/SDH and FEC. They accept fundamental parallel resonant mode crystals from 12MHz to 25MHz. GND       VDD PL602-3x  Selectable 750kHz to 800MHz range. Low phase noise output  -127dBc/Hz for 155.52MHz @ 10kHz offset  -115dBc/Hz for 622.08MHz @ 10kHz offset LVCMOS (PL602-37), LVPECL (PL602-35 and PL602-38) or LVDS (PL602-39) output. 12MHz to 25MHz crystal input. No external crystal load capacitors required. Output Enable selector. Selectable /16 to x32 frequency divider/multiplier. 3.3V operation. Available in 16-Pin TSSOP or 16-pin 3x3mm QFN GREEN/RoHS compliant packages.

PLL (Phase Locked Loop) CLKC CLKT Internal pull -up On QFN package, PL 602-35/-38 do not have SEL0 available: Pin 10 is VDD, pin 11 is GND. However, PL602-37/-39 have SEL0 (pin 10), and pin11 is VDD. See pin assignment table for d etails. Note: On QFN package there is a large center pad for thermal relief. This pad needs to be connected to GND.
