Components: LVDS Squelches Noise In Pair Of Oscillators

Aug. 23, 2004

Low noise, made possible by low-voltage differential signaling (LVDS), sets the F4700/4710 crystal oscillators apart from others. Coming in supply voltages of 3.3 V ±5% (F4700) and 2.5 V ±5% (F4710), they offer a differential output voltage of 0.247 to 0.454 V. Frequency stabilities include ±100, ±50, ±25, and ±20 ppm. Standard frequency ranges from 70 to 170 MHz, with available frequencies reaching 250 MHz. Standard operating temperature ranges from 10°C to 85°C with an optional temperature range of 40°C to 85°C available for most models. The package measures 7 by 5 mm. Pricing for a ±100-ppm F4700 at 212.5 MHz starts at $15.95 in 10,000-unit lots. Delivery is in 12 weeks.
