Device operation
The STCD1020, STCD1030 and STCD1040 are 2, 3 or 4 buffered unity gain clock
distribution circuits. They accept the clock input from an external clock source and send 2, 3
or 4 buffered outputs to different devices.
Each clock output of the STCD1020, STCD1030 and STCD1040 can be enabled for the
device connected to it. If the device connected is in standby and does not require a clock,
the buffer can be disabled to save power consumption. If all the devices connected are in
standby, the STCD1020, STCD1030 and STCD1040 will also be put into standby mode for
further power consumption saving. The enable signals and output clock signals truth table
are given in Table 3.
The input DC cut capacitor is embedded in STCD1020, STCD1030 and STCD1040. A
capacitor outside is needed for each of the clock outputs. The STCD1020, STCD1030 and
STCD1040 are internally biased at 1/2 VCC DC voltage level at the outputs.
Note:
"0" means logic low and "1" means logic high. When NO CLOCK outputs, the CLKx pins
stay at High Impedance.
