Data Sheet High Sensitivity 10Gb/s surface mount coplanar APD preamp receiver AT10XGC The AT10XGC receiver consists of an avalanche photodiode, a low-noise preamplifier and a precision NTC thermistor in a hermetic coplanar packagewith a connectorized single-mode fiber pigtail. Differential outputs are provided to improve noise rejection for enhanced sensitivity. It has been optimised for use in 10Gb/s metro or long-haul applications, either as a discrete device or within a transponder, using NRZ modulation, with or without FEC, at data rates up to 10.709Gb/s. Features: • High sensitivity, -28.5dBm typical • Low capacitance high speed InGaAs APD photodetector • Supports FEC rates up to 10.709Gb/s • Best in class power consumption, only 300mW • Designed to exceed the environmental requirements of Telcordia GR-468-CORE • RoHS 5/6 compliant Applications: • Client or line side links • 300 pin LR transponder applications • Yellow fiber pigtail for MSA compliance 1 Data Sheet Operating Characteristics Case Temperature = 25°C unless otherwise specified Parameter Typ Max Unit 231-1 PRBS BER<10-12 Voptimal = VM10 -28.5 -27.0 dBm Sensitivity penalty EOL over temperature   231-1 PRBS BER<10-12 Voptimal = VM10 T=0 to +85°C 0.75 1.0 dB Deviation from linear phase DC - 6GHz -10 +10 ° VAPD=VM10 Small signal 8 Optical sensitivity BOL   Symbol Measurement Conditions Sens High frequency -3dB corner fH Low frequency -3dB corner fL Transimpedance gain TZ Small signal VOUT 9 GHz 40 kHz 5.7 kΩ Peak-to-peak 165 mV S22 DC to 6.0GHz -8 dB PSAT 2^23-1 PRBS VAPD=VM3 BER<10-12 -3 APD breakdown voltage Vbr T=25°C IAPD=10mA 20 40 V APD breakdown voltage temperature coefficient TVbr 0.030 0.061 V/°C Dark current Id 100 nA Amplifier bias current Icc 73 mA Input current for output limiting IIn lim Transimpedance amp supply voltage VTZA Thermistor resistance RTH    Maximum output voltage Return loss Optical overload         2.3 4.0 -1 At 90% of Vbr 55 Peak-to-peak T=25°C Notes: 2 Min Optical Wavelength between 1525-1575nm.
