DESCRIPTIONS The PLL602-35 (PECL with inverted OE), PLL602-37 (CMOS), PLL602-38 (PECL), and PLL602-39 (LVDS) are high performance and low phase noise XO IC chips.
They provide phase noise performance as low as –125dBc at 1kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x.
They accept fundamental parallel resonant mode crystals from 12 to 25MHz.
