DESCRIPTION
The PL502-35 (LVPECL with inverted OE), PL502-37 (LV
CMOS), PL502-38 (LVPECL), and PL502-39 (LVDS) are high performance and low phase noise VCXO IC chips. They provide phase noise performance as low as –125dBc at 10kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x. The wide pull range (±200 ppm) and very low jitter make them ideal for a wide range of applications, including SONET/SDH a...
