SCAN928028
8 Channel 10:1 Serializer with IEEE 1149.1 and At-Speed
BIST
General Description
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 deseri-
alizer checks the data pattern for bit errors and reports any
errors on the test verification pins on the deserializer.
For additional information - please see the Applications
Information section in this datasheet.
