HMC6590 v02.1014 43 Gbps Transimpancede a mpliifre Typical Applications Features The HMC6590 is ideal for: Supports data rates up to 43 Gbps 40 GbE-FR Internal DCA feedback with external adjustment option 40 GBps VSR / SFF 4 Kohm differential transimpedance gain Short, intermediate, and long-haul optical receivers Low-power dissipation < 300 mW -10.5 dBm optical input sensitivity +5 dBm optical overload Small die size: 1.15 mm x 1.21 mm x 0.15 mm Functional Diagram General Description The HMC6590 is a high-speed, high gain, low-power limiting transimpedance amplifier (TIA) used in optical receivers with data rates up to 43 Gbps. It features low input referred noise, 36 GHz bandwidth, 4 kohm differ- ential small signal transimpedance and output cross point adjustment. HMC6590 exhibits an optical input dynamic range between -10 dBm and +5 dBm while maintaining 10e-12 BER at 43 Gbps operation. The HMC6590 is available in die form, includes an on-chip VCC bypass capacitor. It requires only supply decoupling capacitor as external component. The HMC6590 requires a single 3.3V 5% supply and it typically dissipates less than 300 mW. The device is characterized for operation from 5 C to +85 C temperature. hi p mp li afiet prsmisnr de cnae For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, Norwood, MA 02062 978-250-3343 tel 978-250-3373 fax Order online at www.analog.com/hittitemw 1 Application Support: Phone: 978-250-3343 or RFMG-apps analog.com a - cHMC6590 v02.1014 43 Gbps Transimpancede a m pl i i f r e Electrical Specifications, T = +25C, Vcc = 3.3V A Parameter Conditions Min.
