Data Sheet 10Gb/s surface mount coplanar APD preamp receiver with integrated MEMS VOA ATV10GC The ATV10GC receiver consists of an avalanche photodiode, a low-noise preamplifier, a MEMS variable optical attenuator (VOA), and a precision NTC thermistor in a hermetic coplanar package with 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, -26.5dBm typical • Integrated MEMS VOA extends overload beyond +10dBm • Low capacitance high speed InGaAs APD photodetector • Supports FEC rates up to 10.709Gb/s • Best in class power consumption, only 350mW • Designed to exceed the environmental requirements of Telcordia GR-468-CORE • RoHS 5/6 compliant Applications: • Client or line side links • DWDM TDM transponder applications 1 Data Sheet Operating Characteristics Case Temperature = 25°C unless otherwise specified Parameter Typ Max Unit 231-1 PRBS BER<10-12 VAPD=VM10 -26.5 -25.0 dBm Sensitivity penalty EOL over temperature   231-1 PRBS BER<10-12 VAPD=VM10 T=-5 to +75°C 0.75 1.0 dB Deviation from linear phase DC - 6GHz -10 +10 ° VAPD=VM10 Small signal 7 7.5 1.1 1.6 Optical sensitivity BOL   High frequency -3dB corner Symbol Measurement Conditions Sens fH Low frequency -3dB corner fL Transimpedance gain TZ Small signal Maximum output voltage6 VOUT Peak-to-peak Return loss S22 DC to 7.0GHz PSAT 0dB Attenuation VAPD=VM3 BER<10-12 -3 With VOA actuated +13 T=25°C IAPD=10mA 25 Optical overload     Optical overload extension APD breakdown voltage Vbr APD breakdown voltage temperature coefficient TVbr Dark current Id 600 0.030 Icc IIn VOA maximum attenuation Att VOA control voltage lim Peak-to-peak 20 40 kHz 2.3 kΩ 700 mV -8 dB dBm dBm 0.045 75 Amplifier bias current GHz -1 At 90% of Vbr Input current for output limiting 40 V 0.061 V/°C 100 nA 95 mA 0.5 mA 30 dB VAtt Attenuation = 20dB 5.5 9 V VOA current lAtt Attenuation = 20dB 6 7.2 mA VOA power dissipation (continuous) PAtt Attenuation = 20dB 33 65 mW From attenuation = 1dB to 20dB 5 10 ms 0.15 dB VOA response time   Polarisation dependent loss PDL VOA unbiased Polarisation dependent loss PDL VOA biased Thermistor resistance RTH T=25°C Notes: 2 Min         Optical Wavelength between 1525-1575nm.
