SCAN928028

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.
