PARAMETER MEASUREMENT INFORMATION
CLKR and CLKX selection requirements for DSP-based applications
1. Note that CLKX and CLKR must be selected as follows:
CLKSEL
– 5 V†
0V
5V
CLKR, CLKX
(BETWEEN 1 MHz to 3 MHz)
= (256) × (frame-sync frequency)
= (193) × (frame-sync frequency)
= (192) × (frame-sync frequency)
DEVICE TYPE
TCM29C13/14/16/17
TCM129C13/14/16/17
TCM29C13/14
TCM129C13/14
TCM29C13/14
TCM129C13/14
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
TCM29C13/14/16/17
TCM129C13/14/16/17
TCM29C13/14
0V
= 1.8528 MHz
TCM129C13/14
TCM29C13/14
5V
= 1.8432 MHz
TCM129C13/14
† _{CLKSEL is internally set to – 5 V for TCM129C16/17 and TCM29C16/17.}
2. Corner frequency at 8-kHz frame-sync frequency = 3 kHz
Therefore, the corner frequency = (3/8) × (frame-sync frequency for nonstandard frame sync).
