2. An XCK input accuracy of ±100 ppm is only acceptable if an accurate line rate reference is provided. If TJAT is left to free-run without a reference, or referenced to a derivative of XCK,
then XCK accuracy must be ±32 ppm. The accuracy of XCK affect the performance of TJAT/RJAT.
3. An XCK input accuracy of ±100 ppm is only acceptable if an accurate line rate reference is provided. If TJAT is left to free-run without a reference, or referenced to a derivative of XCLK,
then XCLK accuracy must be ±32 ppm. The accuracy of XCLK affect the performance of TJAT/DJAT.
4. For T1 mode with 2.048Mb/s back-plane data rate only.
Physical And Electrical Specifications
The RST must be asserted for a minimum of 100 ns after XCLK is stable to ensure that the chip is completely reset.
