TSA5520; TSA5521

Table 15 27-bit sequence (fosc = 750 MHz, BS1 = ON, N = 640, Icp = 60 µA, no test function)

000101110101001100010001000

The reference divider is automatically set to 1024 unless RSB has been programmed to 0 during a 27-bit sequence.

This sequence sets RSA = RSB = 0; CP = 0.

Table 16 19-bit sequence

0001010111011100000

This sequence will program fosc to 600 MHz in 50 kHz steps. ICP remains at 60 µA.

Table 17 18-bit sequence

000110111011100000

This sequence will program fosc to 600 MHz in 50 kHz steps. ICP remains at 60 µA.

Table 18 27-bit sequence (fosc = 650 MHz, BS1 = ON)

000110100010100000011001010

This sequence sets RSA to 0, RSB to 1 and CP to 1. After this sequence ICP = 280 µA, N = 1024 (19-bit transmission)

and N = 512 (18-bit transmission), RSB = 1.

Example of 3-wire bus sequence (TSA5521; SW = OPEN)

Table 19 19-bit sequence (fosc = 700 MHz, BS3 = ON)

0100011011010110000

N = 640 unless RSB has been programmed to 0 during a 27-bit sequence.
