Optical Module CDRs
Semtech’s dual-lane signal conditioners, with integrated VCSEL, DML or EML driver, offer the lowest
power, smallest footprint solution for XFP and retimed SFP+ modules.
Enabling SFP+ SONET
Low Cost, Small Footprint Solution
The GN2042 and GN2044 enable a SONET compliant
module in an SFP+ form factor. The integration of the laser
driver enables the lowest power solution for SFP+. The high
level of integration also delivers a small footprint solution
to fit within the form factor. The reference clock free
architecture simplifies the overall module design and saves cost.
By integrating the limiting amplifier, laser driver and
receive and transmit CDR, the GN2042, GN2044 and
GN2017A provide an optimal path for lower cost designs.
The integrated APC loop and small number of external
components also save cost. The high level of integration in a
small, 5mmx5mm 32-QFN package enables use in very high
density designs.
Feature set for DWDM applications
The GN2040 family has a rich feature set to enable optimal
performance in DWDM applications. The features include
slice level adjust, programmable peaking on the receive path
input and sampling clock phase adjust.

13 Semtech 2014 Guide • Optical and IC Products for High-Speed Communications
Backplane & Linecard Signal Conditioners
Semtech’s multi-channel signal conditioners enhance the reach and robustness of high-speed serial
links by compensating for transmission losses and re-setting the crosstalk and jitter budgets.
High Level of Integration and Small Footprint
Reset the Jitter and Crosstalk Budgets
Semtech’s backplane & linecard signal conditioners are ideal
for small form factor modules or dense backplane /linecard
applications.
Using CDRs will reset the jitter budget, substantially
increasing the robustness of the system and allowing for
design flexibility. Using CDRs in multi-channel systems
will also reset the crosstalk budget, an increasing concern at
higher data rates.
Full Portfolio
Semtech products offer solutions for Ethernet, Infiniband®,
Fibre Channel® and PCI Express®. Solutions are available with
and without CDR functionality.
Drive Long Backplanes or Cables
A combination of Equalizer, DFE and CDR technology
allows for an optimal solution to drive long, dense
backplanes or cables at high speeds.

Optical Module
Reference Design Kit
Improve the performance and time to market of your SFP+ design with Semtech Optical Module
Reference Design Kits.
Fast Time to Market
Broad range of reference designs available
Semtech’s reference design kits include schematics, layout
files and a design guide as well as attentive support from
experienced applications engineers. This reduces both design
costs and decreases time to market. This is further realized
in the FTTx market where it is possible to re-use the 10G
symmetric SFP+ design to address the 10G asymmetric
market.
Reference design kits are offered to cover a wide variety of
SFP+ applications, including symmetrical and asymmetrical
PON, and 10 GbE SR and LR applications.
GN1157 RDK (RDK-SFP+-Optical02)
For ethernet SFP+, designs are available for both the
traditional architecture (including a limiting amplifier in the
receive chain), as well as a new LA-free architecture enabled
by Semtech’s High Gain ROSA portfolio.

Semtech 2014 Guide • Optical and IC Products for High-Speed Communications CDR-based Copper Cable Assembly
Reference Design Kits
SFP+ copper cable assembly reference design kits (RDK) based on Semtech’s industry leading 8 Gbps
and 10 Gbps CDR technology.
Fast Time to Market
CDR Advantage
Semtech’s reference design kits include schematics, layout
files and a design guide as well as attentive support from
experienced applications engineers. This reduces both design
costs and time, to get to market quickly.
There are multiple advantages to a CDR-based copper cable
assembly. By resetting the jitter budget in the connector, the
cable’s performance will be independent of the system it is
plugged into. It allows for longer trace lengths and reduces
overall crosstalk in the system.
Multiple Evaluation Options
The RDKs are available in two forms, with or without
attached cable. The version with attached cable can be
immediately plugged into a system or test set up for quick
evaluation. The version without attached cable comes as
a set of two populated PCBs with housing, wherein any
manufacturer’s cable can be soldered onto the PCBs for a
custom evaluation.
