CXB1572Q

CXB1572Q Post amplifier for Optical Fiber Communication Receiver Description The CXB1572Q achieves the 2R optical-fiber communication receiver functions (Reshaping and Regenerating) on a single chip. This IC is also equipped with the signal interruption alarm output function, which is used to discriminate the existence of data input. 32 pin QFP (Plastic) Features Auto-offset canceler circuit Signal interruption alarm output 2-level switching function of identification maximum voltage amplitude for alarm block Single 3.3 V power supply Applications FDDI SONET/SDH ESCON Fiber channel ATM : 125 Mb/s : 155.52 Mb/s : 200 Mb/s : 265.625 Mb/s : 155.52 Mb/s Absolute Maximum Ratings Supply voltage Storage temperature Input voltage difference : I VD – VD I SW input voltage Output current (Continuous) (Surge current) VCC – VEE Tstg Vdif Vi IO –0.3 to +7.0 –65 to +150 0 to +2.5 VEE to VCC 0 to 50 0 to 100 V °C V V mA mA Recommended Operating Conditions Supply voltage VCC – VEE Termination voltage (for data/alarm) VCC – VT1 Termination voltage (for alarm 2) VT2 Termination resistance (for data/alarm) RT1 Termination resistance (for alarm 2) RT2 Operating temperature Ta Structure Bipolar silicon monolithic IC 3.0 to 3.6 1.8 to 2.2 VEE 46 to 56 460 to 560 –40 to +85 V V V Ω Ω °C Sony reserves the right to change products and specifications without prior notice.
