FEATURES

• 622 Mbits/s data input, both Current-Mode Logic (CML)
and Positive Emitter-Coupled Logic (PECL) compatible
(800 mV peak-to-peak maximum)

and ZERO levels

• Optional external (non-adaptive) control of laser
modulation and biasing currents

• Automatic Laser Shutdown (ALS)

• Few external components required

• Rise and fall times typically 120 ps

• Jitter <50 mUI peak-to-peak

• RF output current sinking capability of 60 mA

• Bias current sinking capability of 90 mA

• Power dissipation typically 475 mW

• Low cost LQFP32 plastic package

• Single 5 V power supply.

TZA3001AHL

• Laser alarm output for signalling extremely low and high
bias current conditions.

TZA3001U

• Naked die version with combined bias alarm and loop
mode functionality.

DESCRIPTION

The TZA3001AHL, TZA3001BHL and TZA3001U are fully
integrated laser drivers for STM4/OC12 (622 Mbits/s)
systems, incorporating the RF path between the data
multiplexer and the laser diode. Since the bias and
modulation control circuits are integrated on the IC, the
external component count is low (only decoupling
capacitors and adjustment resistors are required).

The TZA3001AHL features an alarm function for signalling
extreme bias current conditions. The alarm low and high
threshold levels can be adjusted to suit the application
using only a resistor. An additional RF data input is
provided with the TZA3001BHL to facilitate remote (loop
mode) system testing.

The TZA3001U is a naked die version for use in compact
laser module designs. The die contains 40 pads and
features the combined functionality of the TZA3001AHL
and TZA3001BHL.

TZA3001BHL

• Loop mode for testing STM4 622 Mbits/s optical
interfaces; CML and PECL compatible.
