AMCC Builds on High-Performance OC-768 Solution Offering with Introduction of
the Industry-Leading 48 Gbps Silicon Germanium Modulator Driver
Integrating an exceptional combination of adjust capabilities including cross point, swing
and bias level, the S76803 provides customers with a flexible, feature-rich solution for
use in electroabsorption modulator and differential Lithium Niobate applica
SAN DIEGO, September 10, 2001 -- Applied Micro Circuits Corp. (AMCC) [NASDAQ:
AMCC] today announced the S76803, the industry-leading OC-768 silicon germanium
(SiGe) modulator driver. Operating at speeds of up to 48 Gbps, this high-performance,
feature-rich device is ideally suited for use in short-reach and long-reach SONET-based
fiber optic data link applications within the MAN and WAN marketplace. Designed for use
in electroabsorption modulators (EAM) and differential lithium niobate (LiN) modulators
(See Figure 1), the S76803 offers a 3.5V (single-ended) and 7V (differential) output
swing. The device's cross point, swing and bias level adjustable output capabilities offer
customers outstanding flexibility and integration while simultaneously maximizing
performance in a single device (See Figure 2).
"The S76803 modulator driver provides one of the key building blocks, which allow
customers to more easily design optical transceiver and transponder modules for the
MAN as the demand for higher speeds continues to grow," said Oswin Schreiber, senior
product marketing manager. "The OC-768 optical link we exhibited at SuperComm 2001
reinforces AMCC's commitment to supplying customers with complete high-speed
solutions for the world's evolving optical networks and delivers on our promise of
providing commercially available silicon devices for 40 Gbps applications."
The S76803 device provides high-speed voltage drive in an EAM or differential LiN
modulator for SONET OC-768 fiber optic transmitters operating up to 48 Gbits per
second. The output features offered with this device adjust and monitor, so that
customers can optimize the device's output drive waveform. As a result, customers need
only apply a single voltage to the driver, which enables the modulator to perform at the
optimal point of operation. For added flexibility, the S76803 allows customers to directly
adjust the driver’s voltage and feed the signal to the optical device without having to
build additional components.
The S76803 features a 50-Ohm input amplifier with a DC cancel circuit allowing for direct
coupling to the input signal. The device's core is a Distributed Limiting Amplifier (DLA)
with high single-ended output swings up to 3.5V (or differential output swings up to 7V
peak-to-peak) and low output reflection coefficient and power dissipation. The output
voltage amplitude, DC bias levels and duty cycle are also externally programmable.
Operating from a single –5.2V (max –6 V) supply, the S76803 can accommodate large
voltage swings and offsets. In addition, the driver's output cross point can be adjusted
between 30% and 70% of peak signals.
