PARAMETER MEASUREMENT INFORMATION
CLK, CLKR, and CLKX selection requirements for DSP-based applications
CLK, CLKR, and CLKX must be selected as follows:
CLKSEL
−5 V
0V
5V
CLK, CLKR, CLKX
(BETWEEN 1 MHz to 3 MHz)
= (256) × (frame-sync frequency)
= (193) × (frame-sync frequency)
= (192) × (frame-sync frequency)
e.g., for frame-sync frequency = 16 kHz
CLKSEL
−5 V
0V
5V
CLK, CLKR, CLKX
(BETWEEN 1 MHz to 3 MHz)
= 4.096 MHz
= 3.088 MHz
= 3.072 MHz
