CF5036 series 2.5V LVPECL Output Oscillator ICs OVERVIEW The CF5036 series are 2.5V operation, differential PECL output oscillator ICs. They support 50MHz to 250MHz 3rd overtone oscillation and 50MHz to 700MHz fundamental oscillation. The devices are fabricated using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LVPECL output buffer to be incorporated on a single chip. The CF5036 series can be used to construct high-frequency PECL output oscillators. FEATURES I I I I I 2.375 to 3.6V operating supply voltage range Operating frequency range (varies with version) • 50MHz to 700MHz fundamental oscillation • 50MHz to 250MHz 3rd overtone oscillation – 40 to 85°C operating temperature range Differential LVPECL output 50Ω output load (terminated to VCC – 2V) 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 (CF5036××) SERIES CONFIGURATION Version CF5036G1 CF5036G2 CF5036A1 CF5036A2 CF5036B1 CF5036B2 CF5036C1 CF5036C2 CF5036D1 CF5036D2 CF5036E1 (CF5036E2) CF5036F1 (CF5036F2) (CF5036V1) (CF5036V2) (CF5036W1) (CF5036W2) Oscillator constants determined by external components (Rf, CXIN, CXOUT) Fundamental Fundamental or 3rd overtone Oscillation mode Recommended operating frequency range*1 [MHz] 50 to 80 Output frequency fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 fO fO/2 80 to 120 100 to 180 150 to 250 250 to 400 400 to 600 600 to 700 80 to 400 400 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. Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail.

Oscillator Equivalent Circuit C0 cancel CXIN XIN RPD1 Rf CXOUT XOUT Oscillator block equivalent circuit The CF5036 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.
