for Fiber Optic Networks up to 622 Mbps
Rev V5
Applications
• APON
• BPON
• ATM/SONET
Features
• Typical –34 dBm sensitivity, +6 dBm saturation at 622 Mb/s when used with 0.9
A/W InGaAs PIN.
(Cpd ≤ 0.5 pF, BER 10^–10)
• Typical differential transimpedance: 65 kΩ
• Fabricated in standard CMOS
• Differential output
• Standard +3.3 Volt supply
• Available in die form only
• Monitor output
• AGC provides dynamic range of 40 dB
• Internal or external bias for photodiode
• PIN or APD sensor
• Same pad layout and die size as M02013/14/15/16
The M02011 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 40 dB. The
high transimpedance gain of 66 kΩ ensures good sensitivity.
For optimum system performance, the M02011 die should be mounted with a GaAs or InGaAs PIN photodetector
inside a lensed TO-Can or other optical sub-assembly.
The M02011 can either bias the PIN diode from the internal regulator, or use an externally biased PIN diode.
A replica of the average photodiode current is available at the MON pad for photo-alignment and 'Loss of Signal'
monitoring.
