(1) PLL lock-up time varies with ERROR release wait time setting (Register 23h/ERRWT). Therefore, lock-up time in this table shows the
value at ERRWT = 11 as the shortest time setting.
(2) Pins: MPIO_A0-A3, MPIO_B0-B3, MPIOC0-C3, RXIN2-RXIN7, MC/SCL, MDI/SDA, MDO/ADR0, MS/ADR1
(3) Pin: RST
(4) Pin: XTI
(5) Pins: RXIN0, RXIN1. Input impedance of RXIN0 and RXIN1 is 20 kΩ (typical). COAX amplifiers are powered on by Register
34h/RX0DIS and RX1DIS = 0. At power down by Register 34h/RX0DIS and RX1DIS= 1 (default), RXIN0 and RXIN1 are internally tied
high.
(6) Pins: MPIO_A0-A3, MPIO_B0-B3, MPIO_C0-C3, SCKO, BCK, LRCK, DOUT, MPO0-1, ERROR/INT0, NPCM/INT1.
(7) Pin: XTO.
