ABB SDCS-IOB-3 3BSE004086R1 Channel smart card

Once LOL is deasserted, the frequency-locked loop is turned off. The PLL/DLL pulls in the VCO frequency the rest of the way until the VCO frequency equals the data frequency. The frequency loop requires a single external capacitor between CF1 and CF2, Pin 14 and Pin 15. A 0.47 µF ± 20%, X7R ceramic chip capacitor with < 10 nA leakage current is recommended. Leakage current of the capacitor can be calculated by dividing the maximum voltage across the 0.47 µF capacitor, ~3 V, by the insulation resistance of the capacitor. The insulation resistance of the 0.47 µF capacitor should be greater than 300 MΩ.

Normal Mode

 In normal mode, the ADN2816 is a continuous rate CDR that locks onto any data rate from 10 Mb/s to 675 Mb/s without the use of a reference clock as an acquisition aid. In this mode, the lock detector monitors the frequency difference between the VCO and the input data frequency, and deasserts the loss-oflock signal, which appears on Pin 16 (LOL), when the VCO is within 250 ppm of the data frequency. This enables the D/PLL, which pulls the VCO frequency in the remaining amount and acquires phase lock. Once locked, if the input frequency error exceeds 1000 ppm (0.1%), the loss-of-lock signal is reasserted and control returns to the frequency loop, which begins a new frequency acquisition starting at the lowest point in the VCO operating range, 10 MHz. The LOL pin remains asserted until the VCO locks onto a valid input data stream to within 250 ppm frequency error. This hysteresis is shown in Figure 15.

INPUT BUFFER 

The input buffer has differential inputs (PIN/NIN), which are internally terminated with 50 Ω to an on-chip voltage reference (VREF = 2.5 V typically). The minimum differential input level required to achieve a BER of 10−10 is 200 mV p-p. LOCK DETECTOR OPERATION The lock detector on the ADN2816 has three modes of operation: normal mode, REFCLK mode, and static LOL mode.
