RFRX8888xPON Video Receiver

The RFRX8888 integrated circuit (IC) performs ultra-low noise transimpedance amplification of the differential input from a high performance 1550 nm optical wavelength photo detector (PD). The RFRX8888 IC's output is linear low distortion RF from 48 MHz to 1002 MHz. The RFRX8888 IC is ideal for 1550 nm optical wavelength RF analog or digital overlay video receive circuitry employed in xPON FTTP ONT triplexer and quadplexer modules. The RFRX8888 IC first stage incorporates on-die bias circuitry, thus simplifying external-to-IC end product design and lowering end product overall assembly cost. It is optimized for operation from a +12 Vdc power supply eliminating the need for a supplemental ONT power supply in most xPON applications. The RFRX8890 IC is available for FTTP applications requiring +5 Vdc power supply operation.
