HFBR-5961LZ/ALZ
Multimode Small Form Factor (SFF) Transceivers for ATM, FDDI, Fast
Ethernet and SONET OC-3/SDH STM-1 with LC connector
Datasheet
Description
The HFBR-5961xxZ transceiver from Avago provides
the system designer with a product to implement
a range of solutions for multimode fiber Fast
Ethernet and SONET OC-3 (SDH STM-1) physical
layers for ATM and other services.
This transceiver is supplied in the industry
standard 2 x 5 DIP style with an LC fiber connector
interface with an external connector shield.
Transmitter Section
The transmitter section of the HFBR-5961xxZ
utilizes a 1300 nm InGaAsP LED. This LED is
packaged in the optical subassembly portion of the
transmitter section. It is driven by a custom silicon
IC which converts differential PECL logic signals,
ECL referenced (shifted) to a +3.3 V supply, into
an analog LED drive current.
Receiver Section
The receiver section of the HFBR-5961xxZ utilizes
an InGaAs PIN photodiode coupled to a custom
silicon transimpedance preamplifier IC. It is
packaged in the optical subassembly portion of the
receiver.
This PIN/preamplifier combination is coupled to a
custom quantizer IC which provides the final pulse
shaping for the logic output and the Signal Detect
function. The Data output is differential. The
Signal Detect output is single ended. Both Data
and Signal Detect outputs are PECL compatible,
ECL referenced (shifted) to a +3.3 V power supply.
The receiver outputs, Data Output and Data Out
Bar, are squelched at Signal Detect deassert. That
is, when the light input power decreases to a
typical -38 dBm or less, the Signal Detect
deasserts, ie. the Signal Detect output goes to a
PECL low state. This forces the receiver outputs,
Data Out and Data Out Bar to go steady PECL
levels high and low respectively.
