CF5037 series 2.5V LVDS Output Oscillator ICs OVERVIEW The CF5037 series are 2.5V operation, LVDS output oscillator ICs. They support 80MHz to 250MHz 3rd overtone oscillation and 80MHz to 700MHz fundamental oscillation. The CF5037 series can be used to construct high-frequency LVDS output oscillators. FEATURES I I I I 2.375 to 3.6V operating supply voltage range Operating frequency range (varies with version) • 80MHz to 700MHz fundamental oscillation • 80MHz to 250MHz 3rd overtone oscillation – 40 to 85°C operating temperature range LVDS output I I I I Standby function • Outputs are high impedance when OE is LOW. (oscillator stops) Power-saving pull-up resistor built-in (pin OE) BiCMOS process Chip form (CF5037××) SERIES CONFIGURATION Version CF5037A1 CF5037B1 CF5037B2*2 CF5037C1 CF5037C2 CF5037D1 (CF5037D2) (CF5037E1) (CF5037E2) (CF5037F1) (CF5037F2) (CF5037V1) (CF5037V2) Oscillator constants determined by external components (Rf, CXIN, CXOUT) Fundamental Fundamental or 3rd overtone Oscillation mode Recommended operating frequency range*1 [MHz] 80 to 120 100 to 180 Output frequency fO fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO 80 to 400 fO/2 150 to 250 250 to 400 400 to 600 600 to 700 *1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. 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. *2. Minimum output frequency: 80MHz Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail.

The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. 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. Oscillator Equivalent Circuit C0 cancel CXIN XIN RPD1 Rf CXOUT XOUT Oscillator block equivalent circuit The CF5037 series oscillator circuit has a C0 cancel circuit built-in to improve the oscillator margin. If power is applied when there is an open circuit between XIN and XOUT, self oscillation may occur, which is not abnormal. Users should confirm that the oscillator operates normally when a crystal unit is connected.

OE HIGH (or open) LOW OUT, OUTN Either fO or fO/2 High impedance Oscillator Normal operation Stopped Power-saving Pull-up Resistor The OE pin pull-up resistance changes in response to the input level (HIGH or LOW). When OE is tied LOW (standby state), the pull-up resistance becomes large, reducing the current consumed by the resistance. When OE is open circuit, the pull-up resistance becomes small, decreasing the susceptibility to the effects of external noise.
