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 and FEC. They accept fundamental parallel resonant mode crystals from 12 to 25MHz. 1 6 1 5 1 4 1 3 1 2 1 1 1 0 SEL0^ / VDD* • • • • • • • 1 VDD / GND* • VDD ABV023x Selectable 750kHz to 800MHz range.
