1 / 10 page CF5037 series SEIKO NPC CORPORATION —1 2.5V LVDS Output Oscillator ICs OVERVIEW The CF5037 series are 2.5V operation, LVDS output oscillator ICs. They support 80MHz to 250MHz 3rd over- tone oscillation and 80MHz to 700MHz fundamental oscillation. The CF5037 series can be used to construct high-frequency LVDS output oscillators. FEATURES I 2.375 to 3.6V operating supply voltage range I Operating frequency range (varies with version) • 80MHz to 700MHz fundamental oscillation • 80MHz to 250MHz 3rd overtone oscillation I – 40 to 85 °C operating temperature range I LVDS output I Standby function • Outputs are high impedance when OE is LOW. (oscillator stops) I Power-saving pull-up resistor built-in (pin OE) I BiCMOS process I Chip form (CF5037 ××) SERIES CONFIGURATION Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail. ORDERING INFORMATION Version Oscillation mode Recommended operating frequency range*1 [MHz] *1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentica- tion. However, the oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
