i7032
+3.3V to +5.0V, 200Mbps Laser-Diode Driver
1. Introduction
1.1. General description
The i7032 is the 3.3V to 5V, 200Mbps laser-diode
driver with automatic power control (APC). Both accept
differential PECL inputs and provide complementary
output currents. A temperature-compensated reference
voltage is provided for laser bias and modulation
current programming. This allows maximum 80mA to
be programmed for bias and modulation current with
two external resistors.
The i7032 provides adjustable temperature-
compensated modulation current to keep the optical
extinction rate within specifications over the operation
temperature range.
The APC circuits incorporated with a monitor
photo-diode and two external resistors maintain laser’s
average power. A failure-monitor output is provided to
indicate when the APC loop is unable to maintain
average power. To prevent laser diode damage, an
integrated soft-start circuit is provided. The output load
can be DC and AC coupled in both 3.3V and 5V
applications.
The i7032 is in 24-pin QFN package.
