DESCRIPTION

The DS92LV8028 integrates eight serializer devices

into a single chip. The DS92LV8028 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

DS92LV8028 operates independently by using

strobes from a single shared PLL.

The DS92LV8028 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 DS92LV8028 includes an

@SPEED TEST function. Each Serializer channel

has the ability internally generated 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.
