PEF24902HV2.1 Product Details

All timing signals are derived from a 15.36 MHz system clock. The 15.36 MHz clock can be provided by the IEC-4-AFE-X Version 3.2 by a crystal based PLL, which is synchronized to either an 8 kHz or a 2048 kHz clock at pin CLOCK. The frequency at pin CLOCK is detected automatically. 

The PLL is set to the nominal frequency either by a POR or by a falling edge at the RES pin. When the reference clock (CLOCK) is applied, the PLL starts to synchronize. 

The 15.36 MHz clock can also be provided externally at pin CL15 without making use of the internal PLL. In this mode the pin XIN must be tied to either VDD or GND. An internal power-on-reset circuitry assures that the pin CL15 is an input until a 15.36 MHz clock is detected at the output of the PLL/oscillator. 

To enable error-free data transport to/from the Quad IEC DFE-T/Q, the clocks DCL and FSC from the IOM®-2-interface must be synchronous to the 15.36 MHz signal. Therefore it is recommended to use the same signal for FSC and as input to CLOCK pin at the IEC4-AFE-X Version 3.2 when the internal PLL is used to generate the 15.36 MHz clock. 

If another clock source is used for CLOCK, e.g. the 2048 kHz DCL, a common time base must be guaranteed. This is usually achieved if FSC is derived from DCL by dividing it directly by 256. 

Any constant phase difference between the time bases of both clocks is possible, but the devices have currently been qualified and released only for using the same FSC signal for the Quad IEC DFE-T/Q and for IEC-4-AFE-X Version 3.2.
