The SCAN928028 integrates eight serializer devices into a single chip. The SCAN928028 can
simultaneously serialize up to eight 10-bit data streams. The 10-bit parallel inputs are LVTTL
signal levels. The serialized outputs are LVDS signals with extra drive current for point-to-point
and lightly loaded multidrop applications. Each serializer block in the SCAN928028 operates
independently by using strobes from a single shared PLL.
The SCAN928028 uses a single +3.3V power supply with a typical power dissipation of 740mW
(3.3V / PRBS / 66 MHz). Each serializer channel has a unique power down control to further conserve
power consumption.
For high-speed LVDS serial data transmission, line quality is essential, thus the
SCAN928028 includes an @SPEED TEST function. Each Serializer channel has the ability to internally
generate a PRBS data pattern. This pattern is received by specific deserializers (SCAN921224) which
have the complement PRBS verification circuit. The deserializer checks the data pattern for bit
errors and reports any errors on the test verification pins on the deserializer.
