The pair of devicesalso features an at-speed BIST mode which allowstheandbetweenDeserializer to be verified at-speed.the Serializerinterconnects(TAP)The SCAN921025 transmits data over backplanes orcable. The single differential pair data path makesPCB design easier. In addition, the reduced cable,PCB trace count, and connector size tremendouslyreduce cost. Since one output transmits clock anddata bits serially, it eliminates clock-to-data and data-to-data skew. The powerdown pin saves power byreducing supply current when not using either device.Upon power up of the Serializer, you can choose toactivateallow theDeserializerto use the synchronization-to-random-data feature. By using the synchronization mode, theDeserializer will establish lock to a signal withinspecified lock times. In addition, the embedded clockensures a transition on the bus every 12-bit cycle.This eliminates transmission errors due to chargedcable conditions. Furthermore, you may puttheSCAN921025 output pins into Tri-state to achieve ahigh impedance state. The PLL can locktofrequencies between 30 MHz and 80 MHz.synchronization modeor
The SCAN921025 and SCAN921226 are a 10-bit Serializer and Deserializer chipset designed to transmit dataover differential backplanes at clock speeds from 30 to 80 MHz. The chipset is also capable of driving data overUnshielded Twisted Pair (UTP) cable.The chipset has three active states of operation: Initialization, Data Transfer, and Resynchronization; and twopassive states: Powerdown and TRI-STATE. In addition to the active and passive states, there are also testmodes for JTAG access and at-speed BIST.The following sections describe each operation and passive state and the test modes.
