The 5087 series are LVDS output oscillator ICs that operate with 300MHz to 700MHz SAW resonators. The series includes devices with
f
0
/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.

*1. 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.

*1. The 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 crystal characteristics and mounting conditions, so the oscillation
characteristics of components must be carefully evaluated.
Note. Since it may influence the reliability if it is used out of range of recommended operating conditions, this product should be used within this range.
