Part # MAX3273 datasheet

Part Manufacturer: Maxim


Part Description: MAX3273 DS

Part Details:

19-2081; Rev 3; 2/07 +3.3V, 2.5Gbps Low-Power Laser Driver MAX3273 General Description Features The MAX3273 is a compact, low-power laser driver for 30mA Power-Supply Current applications up to 2.7Gbps. The device uses a single Single +3.3V Power Supply +3.3V supply and typically consumes 30mA. The biasand modulation current levels are programmed by Up to 2.7Gbps (NRZ) Operation external resistors. An automatic power-control (APC) Automatic Average Power Control with Failure loop is incorporated to maintain a constant average Monitor optical power over temperature and lifetime. The laserdriver is fabricated using Maxim s in-house, second- Programmable Modulation Current from 5mA to generation SiGe process. 60mA The MAX3273 accepts differential CML-compatible Programmable Bias Current from 1mA to 100mA clock and data input signals. Inputs are self-biased to Typical Fall Time of 59ps allow AC-coupling. An input data-retiming latch can be Selectable Data Retiming Latch enabled to reject input jitter if a clock signal is available. The driver can provide bias current up to 100mA and Complies with ANSI, ITU, and Bellcore modulation current up to 60mA SDH/SONET Specifications P-P with typical (20% to 80%) edge speeds of 59ps. A failure-monitor output isprovided to indicate when the APC loop is unable to Ordering Information maintain average optical power. The MAX3273 is avail-able in 4mm 4mm, 24-pin QFN and thin QFN pack- PIN- PACKAGE PART TEMP RANGE ages, as well as in die form.
