5086 series 2.5V LV-PECL Output Oscillator ICs OVERVIEW The 5086 series are differential LV-PECL output oscillator ICs that operate with 300MHz to 700MHz SAW resonators. The series includes devices with fo/4 frequency output (mask option), making them ideal for lowfrequency 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 LV-PECL output oscillator optimal to use in high-speed serial interface applications.

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) 0.01µF RN732ATTD49R9B25 (KOA) 49.9Ω Measurement Circuit 1 Measurement parameter: ICC, ISTB, IIH, IIL, VIH, VIL 0.01µF (Ceramic chip capacitor) ICC, ISTB A VCC1 XOUT VCC2 OUT 49.9Ω VT 49.9Ω XIN OUTN OE GND1 GND2 VCC−2V IIH, IIL A 0.01µF (Ceramic chip capacitor) VIH,VIL Measurement Circuit 2 Measurement parameter: VOH, VOL 0.01µF (Ceramic chip capacitor) VCC1 XOUT VCC2 OUT 49.9Ω Signal Generator 0.01µF VOH,VOL 49.9Ω XIN 49.9Ω VT OE OUTN GND1 GND2 VCC−2V 0.01µF (Ceramic chip capacitor) Input signal: 500mVp-p, sin waveform, 10MHz to 40MHz SEIKO NPC CORPORATION —8 5086 series Measurement Circuit 3 Measurement parameter: IZ 0.01µF (Ceramic chip capacitor) VCC1 VCC2 OUT XOUT IZ A SW1 IZ XIN OUTN OE GND1 GND2 A Measurement Circuit 4 Measurement parameter: Duty1, Duty2, VOPP , tr , tf 0.01µF (Ceramic chip capacitor) VCC1 VCC2 OUT XOUT 49.9Ω VT Duty1 (Differential) 49.9Ω XIN OE OUTN GND1 GND2 VCC−2V Duty2,VOPP,tr,tf (Single ended) 0.01µF (Ceramic chip capacitor) Measurement Circuit 5 Measurement parameter: tOD 0.01µF (Ceramic chip capacitor) VCC1 XOUT VCC2 OUT 49.9Ω Signal Generator 0.01µF XIN 49.9Ω VT Output signal 49.9Ω OE OUTN GND1 GND2 VCC−2V 0.01µF (Ceramic chip capacitor) Input signal: 500mVp-p, sin waveform, tOD: OE = VCC to GND SEIKO NPC CORPORATION —9 5086 series FUNCTIONAL DESCRIPTION Standby Function When OE goes LOW, the oscillator stops and the output pins (OUT, OUTN) become high impedance. OE OUT, OUTN Oscillator HIGH (or open) Any fO, fO/2 or fO/4 output frequency Normal operation LOW High impedance 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 Detector Function The 5086 series also feature an oscillation detector circuit. This circuit functions to disable the outputs until the oscillator circuit starts and oscillation becomes stable. This alleviates the danger of abnormal oscillator output at oscillator start-up when power is applied or when OE is switched.
