HiLight Semiconductor releases HLR11G0 10-Gbps CMOS TIA for PIN photodiodes
HiLight Semiconductor says it now offers the HLR11G0 10-Gbps high-sensitivity transimpedance amplifier (TIA). The device can achieve sensitivity levels of -22 dBm for use in medium distance optical links with standard PIN photodiodes. Example applications include 10- to 40-km mobile network optical interconnects and datacom links for LR, ER, and CWDM applications.
The HLR11G0 has been designed for use with a wide range of photodiode capacitances without the need for compensation settings. A transimpedance gain of 6.2 kΩ ensures high output swing levels, coupled with a low noise front end and optimized bandwidth. The TIA also features internal digital temperature control of key parameters for high performance across the industrial operating temperature range. The CMOS based HLR11G0 operates from a single +3.3 V power supply and has a typical current consumption of 26 mA.
HiLight says that, when coupled with 10G photodiodes from Optosensor (OS-PD1050B) and Phograin (XJS-10-D5-SPI), the HLR11G0 repeatedly achieved -22 dBm (1E-12) with an IRN of 608 nA rms. The HLR11G0 thus can enable increased link budget margin for photodiode applications and improved manufacturing yields for optical sensitivity tests.
The HLR11G0 also features adjustable 5.1-kΩ to 6.2-kΩ transimpedance gain, single or dual cathode PD connections, and internally generated and regulated photodiode bias supply with RSSI monitor output and overload performance of better than +3 dBm, according to the company. The TIA measures 0.7x1.05 mm, which enables it to fit easily within a standard TO-can
“By delivering a 2-dB improvement over current state-of-art TIAs the HLR11G0 delivers world-class sensitivities for 10G mid-distance datacom or CPRI wireless optical link applications and can be used with HiLight’s existing portfolio of CMOS DML laser driver transceiver combo ICs to realize highly integrated, low power, and economical optical transceiver modules,” stated Christian Rookes, vice president, marketing at HiLight.
