5087 series LVDS Output Oscillator ICs OVERVIEW The 5087 series are LVDS output oscillator ICs that operate with 300MHz to 700MHz SAW resonators. The series includes devices with f0/4 frequency output (mask option), making them ideal for low frequency SAW oscillators as low as 75MHz. They are specialized for SAW oscillators, realizing smaller chip size compared to existing products. They feature low jitter, miniature LVDS output oscillator to use in high-speed serial interface applications. FEATURES ▪ 2.375 to 3.6V operating supply voltage range ▪ Recommended oscillation frequency range: 300MHz to 700MHz (varies with version) ▪ Output frequency range: 75MHz to 700MHz f0,f0/2,f0/4 output frequency, determined by internal connection ▪ Output rise time/Output fall time: 400ps (max) ▪ -40 to +85°C operating temperature range ▪ LVDS output ▪ Standby function Outputs are high impedance when OE is LOW.

It becomes WF5087xx in case of the wafer form and CF5087xx in case of the chip form. *2. The recommended oscillation frequency is a yardstick value derived from the resonator used for NPC characteristics authentication. However, the oscillation frequency range is not guaranteed. Specifically, the characteristics can vary greatly due to resonator characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated. *3. The built-in oscillation capacitance contains parasitic capacitance.

Load resistance specified in each measurement circuit below should be connected to OUT and OUTN pins (excluding measurement circuit 3). Circuit wiring of bypass capacitors and load resistance should be connected as short as possible. If the circuit wiring is long, the required characteristics may not be realized. Also, if the values of bypass capacitors and load resistance differ from the description in this document or are not connected, the required characteristics may not be realized. * The capacitor and resistor used in measurement circuits below; GRM155F11H103Z (MURATA) 0.01F GRM1552C1H102JA01 (MURATA) 1000pF RN732ATTD49R9B25 (KOA) 49.9Ω The differential probe spec used for measurement recommends >5GHz analog bandwidth, >50kΩ impedance, and <1pF load. If common-mode noise becomes a problem, connect a capacitor between the center tap of 49.9Ω resistance and GND. The capacitor should choose value so that impedance becomes low on the frequency of the noise which is attenuated.

OE OUT, OUTN Oscillator HIGH (Open) Any f0, f0/2, f0/4 output frequency Operating LOW Hi-Z 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. Oscillation Detection Function The 5087 series also feature an oscillation detector circuit. This circuit functions to disable the outputs until the oscillator circuit starts and the oscillation becomes stable. This alleviates the danger of abnormal oscillator output at oscillator start-up when power is applied or when OE is switched.
