Notes
1. Default settings: UI = LOW (pre-programmed mode; see Table 1); DR0 = LOW, DR1 = HIGH, DR2 = LOW
2. The total supply current and power dissipation is dependent on the I
3. ENLOUTQ = LOW (DLOOP, CLOOP enabled); ENLINQ = LOW (DIN, CIN enabled) and maximum output swing;
4. The output swing is adjustable in 16 steps controlled by bits RFS in the I
5. For multiplexing ratio 10:1, the I
6. The output swing is adjustable in 16 steps controlled by bits MFS in the I
7. Reference frequency of 19.44 MHz, with a phase-noise of less than 140 dBc for frequencies of more than 12 kHz
8. For bit rates lower than 1.8 Gbits/s, the jitter decreases with the octave division ratio.
