Serial Data Input Timing There are several other considerations for programming: • The DATA is clocked into a shift register on each rising edge of the CLK signal. On the rising edge of the LE signal, the data is sent from the shift register to an actual counter. • If no LE signal is given after the last data bit and the clock is kept toggling, then these bits will be read into the next lower register. This eliminates the need to send the address each time. • A slew rate of at least 30 V/us is recommended for the CLK, DATA, and LE signals • Timing specifications also apply to readback. Readback can be done through the MUXout, TRIG1, TRIG2, or MOD terminals. 6 Submit Documentation Feedback Copyright © 2014–2015, Texas Instruments Incorporated Product Folder Links: LMX2492 LMX2492-Q1 |
