XPD0250CT-001

www.DataSheet4U.com 2.5 Gbps PIN-TIA module XPD0250CT-001 FEATURES Wide dynamic range, typically 6µW to 1.7mW (p-p) Differential transimpedance of 4㏀ Bandwidth from DC to 1.9GHz Differential outputs On-chip Automatic Gain Control(AGC) Single supply voltage 3.3V Remains linear up to 1.7mW(p-p) input current(unclipped) AGC CHARACTERISTICS The XPD0250CT-001 can handle input optical power from 6µW to 1.7mW which is equivalent to a dynamic range of 49dB. At low input optical power, the transimpedance gain ZT must be high to obtain enough output voltage, and the noise should be low enough to guarantee a minimum bit error rate. The transimpedance is regulated from 4 ㏀ at low input optical power (Po<30µW) to 80Ωat high power (Po =1.7mW). APPLICATIONS Digital fiber optic receiver in short, medium and long haul optical telecommunications transmission systems or in high speed data networks Wide-band RF gain block ELECTRICAL CHARACTERISTICS (TC = 25℃) Parameter Power supply voltage Power supply current Photodiode bias voltage* Transimpedance 3dB Bandwidth Transimpedence gain deviation Electrical return loss Responsivity Output impedence Symbol VCC ICC VPD ZT f3dB ΔZT LE R ZO Test Condition RL=50Ω, measured differenctially, AC coupled Min. 3.0 3.3 Typ. 3.3 26 Max. 3.3 37 5 Unit V mA V KΩ GHz 4 1.7 1.9 2 -10 0.85 50 Pin=-10dBm f=1MHz to 1.8GHz λ = 1550nm - dB dB A/W Ω * Photodiode bias is necessary only for 5 pin type module.
