PARAMETER MEASUREMENT INFORMATION

CLKR and CLKX selection requirements for DSP-based applications

CLKX and CLKR must be selected as follows:

CLKSEL

CLKR, CLKX

(BETWEEN 1 MHz to 3 MHz)

DEVICE TYPE

5V†

= (256)

× (frame sync frequency)

TCM29C13A/14A/16A/17A

– 5 V†

= (256)

× (frame-sync frequency)

TCM129C13A/14A/16A/17A

0V

= (193)

× (frame sync frequency)

TCM29C13A/14A

0 V

= (193)

× (frame-sync frequency)

TCM129C13A/14A

5V

= (192)

× (frame sync frequency)

TCM29C13A/14A

5 V

= (192)

× (frame-sync frequency)

TCM129C13A/14A

† CLKSEL is internally set to – 5 V for TCM29C16A/1A7 and TCM129C16A/17A e.g., for

frame-sync frequency = 9.6 kHz

CLKSEL

CLKR, CLKX

(BETWEEN 1 MHz to 3 MHz)

DEVICE TYPE

5V†

= 2 4576 MHz

TCM29C13A/14A/16A/17A

– 5 V†

= 2.4576 MHz

TCM129C13A/14A/16A/17A

0V

= 1 8528 MHz

TCM29C13A/14A

0 V

= 1.8528 MHz

TCM129C13A/14A

5V

= 1 8432 MHz

TCM29C13A/14A

5 V

= 1.8432 MHz

TCM129C13A/14A

† CLKSEL is internally set to – 5 V for TCM29C16A/1A7 and TCM129C16A/17A.

Corner frequency at 8-kHz frame-sync frequency = 3 kHz, therefore, the corner frequency = (3/8)

× (frame-sync

frequency for nonstandard frame sync).
