... TM © 2005 Fairchild Semiconductor Corporation FIN24AC Rev. 1.0.3 General Description The FIN24AC µSerDes™ low-power Serializer/ Deserializer (SerDes) that can help minimize the cost and power of transferring wide signal paths. Through the use of serialization, the number of signals transferred from one point to another can be significantly reduced. ...

The DSO/DSI serial port terminals have been arranged such that when one device is rotated 180° to the other device, the serial connections properly align without the need for any traces or cable signals to cross. Other layout orientations may require that traces or cables cross. © 2005 Fairchild Semiconductor Corporation FIN24AC Rev. 1.0.3 Number of Terminals Description of Signals ...

... Control Logic Circuitry The FIN24AC has the ability to be used as a 24-bit Seri- alizer or a 24-bit Deserializer. Pins S1 and S2 must be set to accommodate the clock reference input frequency range of the serializer. Table 1 shows the pin program- ming of these options based on the S1 and S2 control pins ...

... No Data Figure 5. Serializer Timing Diagram (CKREF does not equal STROBE) © 2005 Fairchild Semiconductor Corporation FIN24AC Rev. 1.0.3 The Phase-Locked Loop (PLL) must receive a stable CKREF signal to achieve lock prior to any valid data being sent. The CKREF signal can be used as the data STROBE signal, provided that data can be ignored during the PLL lock phase ...

Serializer Timing Diagram Using Provided Bit Clock (No CKREF) © 2005 Fairchild Semiconductor Corporation FIN24AC Rev. 1.0.3 (Continued) A third method of serialization can be accomplished with a free running bit clock on the CKSI signal. This mode is enabled by grounding the CKREF signal and driving the DIRI signal HIGH. ...
