NOTES:
1. RX+ and RX– left open circuited.
2. Jitter present at TXTIP and TXRING with no jitter at TCLK (LB=0) or LCLK (LB=1).
3. Measured with 100 ohm (
±
5%) termination at TXTIP and TXRING.
4. Measured directly at TXTIP and TXRING with 0 dB of line build out.
5. Pulse shape meets template in Figure 3 over temperature and voltage.
6. Measured over 17 consecutive pulses.
7. Measured in a 2 KHz to 3 KHz band about 772 KHz; power level in a 2 to 3 KHz band at 1.544 MHz is at least
25 dB lower.
