Coherent Unveils Innovative 100G Transimpedance Amplifiers
Coherent Corp. (NYSE: COHR), a recognized leader in the field of photonics, has recently announced a significant addition to its product lineup. With a focus on enhancing the capabilities of optical transceivers, Coherent introduces the 56 Gbaud PAM4 transimpedance amplifier (TIA) as part of its open-market ASIC portfolio.
Key Features of the CHR1065 Amplifier
This newly launched CHR1065 product family is specifically engineered for next-generation 400G and 800G optical transceivers. It promises remarkable performance along with practical advantages at the system level. One of its standout features is the industry-leading input-referred noise level of only 2 µARMS. This exceptional value translates to enhanced receiver sensitivity, allowing for greater optical reach without compromising performance.
Efficiency and Versatility
Another important aspect to highlight is the high linearity of the CHR1065, which can handle up to 2.5 mA. This capability ensures reliable performance across various operating conditions and link budgets, making it a versatile choice for developers. In terms of power consumption, the amplifier operates at just 227 mW per channel, which is a significant advantage for power-constrained data centers. This allows for dense deployments without the accompanying operational costs and cooling requirements typically associated with high-performance components.
System Integration and Monitoring
The CHR1065 incorporates advanced features such as a 750 µm optical pitch and sophisticated monitoring through an I2C interface. These innovations facilitate seamless integration of up to four devices, which is an asset for compact designs in data communication, including direct connect (DR), short-range (FR), and long-range (LR) modules.
Insights from Coherent Leadership
Dr. Beck Mason, Executive VP of Semiconductor Devices at Coherent, stated that the introduction of this amplifier reflects the company's ongoing commitment to expand its comprehensive fiber-optic ASIC portfolio. He mentioned that the CHR1065 is just the beginning, with upcoming products expected to include even higher bandwidth options, such as 112 GBaud ASICs and 224 GBaud models.
Availability and Production Details
The CHR1065 amplifier is currently available as a wire-bondable bare die and has completed its transition to volume production. For engineers interested in sampling this new technology, units are now shipping in convenient 25-piece waffle packs. With decades of reliable deployment in Coherent's optical transceivers, customers can expect proven design reliability backed by JEDEC-standard lifetime testing.
