ISL58113 Features The ISL58113 is a high-performance laser driver that provides controlled current to grounded laser diodes. A bias current is summed with the switched current at the IOUT output, allowing the user to optimize laser diode performance. * Voltage-controlled Output Current Source Output switched current flows when the LVDS signal DATA is high. The output current returns to the fixed-threshold value when DATA is low. Complete IOUT shut-off is achieved by holding the CHPEN low, which will override all other control pins. * Very Few External Components Needed * Internal LVDS Termination Resistors * 200MHz Switching * Up to 70mA Output Current * Rise Time < 500ps * Fall Time < 500ps * APC Loop for Write Power Control * Fast Settling APC Amplifier A fast settling APC amplifier connects directly to the monitor diode. The ISL58113 does not exhibit any time-dependent droop since the calibration gain is stored as a digital number. * Single +3.3V Supply (10%) Ordering Information * Pb-Free (RoHS compliant) PART NUMBER (Notes 1, 2) ISL58113CRZ-T13 PART MARKING 58113 CRZ PACKAGE Tape & Reel (Pb-free) 24 Ld QFN PKG. DWG. # L24.4x5B * Disable Feature for Power-Up Protection and Conserving Power * Zero Droop Load Configuration * Common-cathode LD, Common-anode PD IOUT PDIN NOTES: 1. Please refer to TB347 for details on reel specifications. 2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
