1.1
Introduction
The demoboard OM5802 is designed to demonstrate the functionality of the following ICs:
In this report, the 622 Mbps ICs will be used. All discussions are valid for the ICs of the different types.
In this section an overview of the board will be given. After this, some measurements will be shown.
1.2
Demoboard description
The receiver section of the board consists of the photodetector, transimpedance amplifier, lowpass filter and
limiter (TZA3000), the data and clock recovery unit (TZA3004) and the demultiplexer (1/2 TZA3005).
The transmitter section consists of the cleanup PLL, the multiplexer and clock convertor (other half of TZA3005),
the laserdriver (TZA3001) and the laserdiode.
For phase alignment & jitter filtering, a cleanup phase locked loop has been added (74HCT9046+19.44 MHz
VCXO).

Test possibilities
1.3.1
1 chip receiver TZA3000
The TZA3000 has 2 outputs (CML and PECL levels). The PECL level outputs are available at SMA connectors.
This gives the user the possibility to test the TZA3000 separate from the rest of the system.
1.3.2
Data and clock recovery unit TZA3004
The TZA3004 has 2 outputs (Normal and Loop). The Normal data and clock outputs are available at SMA
connectors. This gives the user the possibility to test the TZA3000 and the TZA3004 combination separate from
the rest of the system. The Loop outputs are connected with the Demux.
If the TZA3005 is not on the board (in case of the 1250 Mbps configurations), the reference clock for the DCR
needs to be provided via REFCLKQ.
1.3.3
Mux/Demux TZA3005
The TZA3005 receiver tests have to be done in conjunction with the TZA3000 and TZA3004. The board does not
contain a separate serial input.
The parallel clock, data and frame outputs are available on pin arrays to connect to a logic analyzer. The frame
alignment enabling is also available to the user. A buffered version of the parallel clock and a copy of the frame
pulse are available on SMB connectors
The TZA3005 transmitter part can be tested apart from the system: the serial data is available on the LDR DIN /
LDR DINQ SMA connectors. The serial clock is attenuated and connected with an SMA connector.
