Power-Up and Reset
Internal power-on-reset circuitry generates a reset during power-up. All registers are reset to the default values.
Writing to the Software Reset Register (SWR) generates at least 1
s reset cycle, which has the same effect as the
power-up reset.
The DS26334 can be reset by a low going pulse on the RSTB pin (see Table 4-1). A reset can also be performed in
software by writing any value to the SWR register.
5.3
Master Clock
The DS26334 requires 2.048MHz ±50ppm or 1.544MHz ±50ppm or multiple thereof. The receiver uses the MCLK
as a reference for clock recovery, jitter attenuation and generating RCLK during LOS. The AIS transmission uses
MCLK for transmit all ones condition. See register MC to set desired incoming frequency. When the PLLE bit is set,
the master clock adapter will generate both 2.048MHz (E1) and 1.544MHz (T1) clocks. If the PLLE bit is clear, both
internal reference clocks will track MCLK.
MCLK or RCLK can also be used to output CLKA on the LOS16 pin. Register CCR is used to select the clock
generated for CLKA and the TECLK. Any RCLK can also be selected as an input to the clock generator using this
same register. For a detailed description of selections available see Figure 5-5.
