HMC690

v04.0709 HMC690 10 Gbps TRANSIMPEDANCE AMPLIFIER TRANSIMPEDANCE AMPLIFIERS - CHIP 5 5-2 Typical Applications Features The HMC690 is ideal for: Supports data rates up to 11.3 Gbps SONET OC-192 and SDH STM-64 Transponders 1.25 Kohm differential gain 10 Gbps Ethernet +3.3 V single power supply Broadband instrumentation AC or DC coupled outputs Short, intermediate and long reach optical receiver modules SOLETE Functional Diagram 11 pA/√Hz input referred noise density 3 mA p-p overload Average input power monitoring Output offset adjustment Die Size: 0.68 x 1.14 x 0.18mm General Description The HMC690 is 10 Gbps transimpedance amplifier designed for SONET OC-192 / SDH STM-64, 10GbE and 10Gbps systems employing optical amplifiers. It supports data rates up to 11.3 Gbps. This amplifier provides a differential output voltage that is proportional to an applied current at its input port. This current is typically provided by a photodiode. Operating from a single +3.3V supply, the HMC690 features low input referred noise, and is designed for driving a CDR or a typical transceiver directly. The RSSI output can be used for monitoring average input power. This device also features a DC offset control, which enables output signal level adjustment for asymmetrical signals. Additional features include an integrated 300Ω filter resistor for photo-diode supply voltage and an extended linear range[2] option.
