10 CXB1586AR notes on operation 1. external loop filters for plls the CXB1586AR has two plls. one is for the transmitter and locks to the reference clock from refclk input pin. another one is for the receiver and locks to the received serial data from sdin/sdin * input pins. they need external capacitors for the their loop filters. typical values of the external capacitors are indicated below. 2. example of power supply circuit 4 9 4 8 c 2 1 7 1 6 c 1 c 1 : 0 . 0 1 f c 2 : 0 . 0 1 f v c c t 3 . 3 v 2 2 f 0 . 1 f v e e t a v c c g v c c e 2 2 f 0 . 1 f v e e g v e e e a 2 2 f 0 . 1 f a v c c p v e e p
