L = LOW, H = HIGH, X = don't care Pin Function VCC, VCCO Separate positive power supply pins help to isolate sensitive circuitry from noise generating function. +5V for PECL operation or ground for ECL operation. VEE Most negative power supply input. Ground for PECL operation or -5V for ECL operation. VBB This pin provides a reference voltage for use in single ended applications or when the input signal is AC coupled into the device. D,D These differential ECL/PECL 100K compatible inputs receive NRZ data. EN This ECL/PECL 100K compatible input enables Laser Driver - modulation current transitions to zero when asserted HIGH. OUT, OUT Open collector outputs from the modulation buffer drive these differential current outputs. MC An external voltage sets the main value of modulation current IO. RSET An external resistor sets the source current for modulation Imod. NC These pins are not connected. Symbol Rating Value Unit VEE Power Supply Voltage (VCC = 0V) 0 to -7.0 V VIN Input Voltage (VCC = 0V) 0 to -6.0 V IOUT Output Current 75 mA TLEAD Lead Temperatre (soldering, 20sec.) +260 °°C TA Operating Temperature Range –40 to +85 °°C Ptot Power Dissipation 500 mW Note: 1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for extended periods may affect device reliability. ABSOLUTE MAXIMUM RATINGS(1) PIN NAMES TRUTH TABLE(1) Symbol Rating Value Unit VEE Power Supply Voltage –4.75 to -5.25 V RSET Resistor to Adjust Current 10 to 100 Ω REXT Resistor to Dissipate Power 10 to 50 Ω RSER Laser Diode Serial Resistor 0 to 50 Ω OPERATIONING CONDITIONS(1) Note: 1. The voltage drop across REXT and RSER should not be greater than 2V. |
