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.

*1. The recommended oscillation frequency is a yardstick value derived from the resonator used for NPC characteristics authentication. However,
the oscillator frequency band 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.
*2. The oscillator internal capacitance values includes parasitic capacitance.

MEASUREMENT CIRCUITS
■
Note: Bypass capacitors specified in each measurement circuit below should be connected between VCC and
GND, and VT and GND. 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.

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.
