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
– 5 V†
= (256) × (frame-sync frequency)
TCM29C13A/14A/16A/17A
TCM129C13A/14A/16A/17A
TCM29C13A/14A
0V
= (193) × (frame-sync frequency)
TCM129C13A/14A
TCM29C13A/14A
5V
= (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
– 5 V†
= 2.4576 MHz
TCM29C13A/14A/16A/17A
TCM129C13A/14A/16A/17A
TCM29C13A/14A
0V
= 1.8528 MHz
TCM129C13A/14A
TCM29C13A/14A
5V
= 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).
