8 / 19 page Specification of control register STLVD111 8/19 4 Specification of control register The STLVD111 is provided with a 11 bit shift register with a Serial In and a Control Register. The purpose is to enable or power of each output clock channel and to select the clock input. The STLVD111 provides two working modality: 4.1 Programmed mode (EN=1) The shift register have a serial input to load the working configuration. Once the configuration is loaded with 11 clock pulse, another clock pulse load the configuration into the control register. The first bit on the serial input line enables the outputs Q9 and Q9, the second bit enables the outputs Q8 and Q8 and so on. The last bit is the clock selection bit. To restart the configuration of the shift register a reset of the state machine must be done with a clock pulse on CK and the EN set to Low. The control register shift register can be configured on time after each reset. 4.2 Standard mode (EN=0) In Standard Mode the STLVD111 isn’t programmable, all the clock outputs are enabled. The LVDS clock input is selected from Clock 0 or Clock 1 with the SI pin as shown in the Truth Table below. Table 10.
