GX8009 can replace AD8009 for optical transmitter with bandwidth up to 1GHz.

Optical communication is the use of optical fiber as a transmission medium, the information will be transmitted through the optical signal in the optical fiber, i.e., fiber-to-circuit, circuit-to-optical fiber signal conversion, signal transmission, HDMI Optical Transceiver is the terminal equipment for optical signal transmission, mainly by the optical transceiver diode, optical signal amplification circuit, clock recovery circuit, synchronization circuit, PCM coding and decoding circuits, and drive circuits and other components.

Optical signal amplification circuits often need to use high-speed op-amps, engineers usually choose to use mainstream devices such as ADI, this article recommends the GXSC single-channel ultra-high-speed current feedback amplifier GX8009, bandwidth of up to 1GHz, compatible with the performance of AD8009.

GX8009 advantageous features:

1. ultra-high speed, pressure swing rate up to 5,500V/µs, rise time is only 545ps, high pressure swing rate can reduce the pressure swing rate limiting effect, so that the large-signal bandwidth up to 440MHz, small-signal bandwidth up to 1GHz, so as to meet the needs of high-resolution video graphics system.

2. High output drive capability, can provide more than 175mA load current, drive four rear terminated video loads; able to provide 10dBm output power (70MHz), no spurious dynamic range (SFDR) of -38dBc

3. Low distortion over a wide bandwidth, enabling signal quality to be maintained at a high level over the entire wide bandwidth range

4. Able to provide more than 175mA load current. When driving four video loads, it can achieve low differential gain and phase error (0.02% and 0.04°, respectively).

5. High drive capability is also reflected in its ability to provide 10dBm of output power, when the frequency of 70MHz when the spurious-free dynamic range (SFDR) of about -38dBc.

6. Available in small SOIC-8 and SOT23-5 packages, with operating temperatures ranging from -40℃ to 85℃.
