5087

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. (oscillator stops) ▪ Power-saving pull-up resistor built-in (OE pin) ▪ BiCMOS process ▪ Wafer form (WF5087xx) ▪ Chip form (CF5087xx) SERIES CONFIGURATION Version*1 Recommended crystal unit/resonator Recommended oscillation frequency range*2[MHz] Built-in capacitance*3[pF] CXIN CXOUT Output frequency 5087A1 f0 5087A2 300 to 500 68 f0/2 5087A3 5087B1 SAW f0/4 f0 5087B2 500 to 700 55 f0/2 5087B3 f0/4 *1.
