Communications Product Highlights Lowest Power SFP
SFP/SFF Optical Module
The MIC3003GFL is a fiber optic module controller which enables the
implementation of sophisticated, hot-pluggable fiber optic transceivers
with intelligent laser control and an internally calibrated Digital Diagnostic
Monitoring Interface per SFF-8472. It essentially integrates all non-data
path functions of an SFP/SFP+ transceiver into a tiny (3mm x 3mm) QFN
package. It also works well as a microcontroller peripheral in transponders or
10Gbps transceivers. The MIC3003GFL uses the same die as the MIC3003
with all its functions, but in a smaller package and different pin out.
Communication with the MIC3003 is via an industry standard 2-wire SMBus
serial interface. Nonvolatile memory is provided for serial ID, configuration,
and separate OEM and user scratchpad spaces.
The SY84782U is a single 2.5V supply, ultra-low power, small form
factor laser diode driver for telecom/datacom applications. Intended to drive
FP/DFB lasers at data rates up to 1.25Gbps, it is especially useful for Compact
SFP, SFP and SFF modules where power requirements are quite stringent.
The driver can deliver modulation current up to 90mA and offers a high
compliance voltage, all of which make the SY84782U suitable for high current
operations in both AC- and DC-coupled applications.
The SY84782U is intended to be used with Micrel’s MIC3003 Optical
Transceiver Management IC, which allows for both modulation and bias
current control and monitoring. Furthermore, the MIC3003 offers power control
and temperature compensation.
The SY84113BU low power limiting post amplifier is designed for use in
fiber-optic optical modules for multirate applications up to 1.25Gbps.
The device connects to a typical transimpedance amplifier (TIA) and can
produce output signals to CML-level waveforms. Intended for use in GbE and
Fibre Channel applications, the SY84113BU offers a wide LOS range. It is
able to detect input signals for as low as 5mV PP and as high as 100mV PP .
The SY84113BU is intended to be used in AC-coupled input applications.
The SY84113BU generates a Loss-of-Signal (LOS) open-collector TTL
output. A programmable Loss-of-Signal level set pin (LOSLVL) sets the
sensitivity of the input amplitude detection. LOS asserts high if the
input amplitude falls below the threshold set by LOSLVL and de-asserts low
otherwise. The enable input (/EN) de-asserts the true output signal
without removing the input signal. The LOS output can be fed back to the /EN
input to implement the squelch function that maintains output stability under a
loss-of-signal condition.
