Recommended Operating Conditions
(T
*IrDA Parameters. The Max Clk Frequency represents the maximum clock frequency to drive the HSDL-7000’s internal state machine.
Under normal circumstances, this clock input should not exceed 16 * 115.2 Kbp/s or 1.8432 MHz. This product can operate at higher
clock rates, but the above is the recommended rate.
The Minimum Pulse Width represents the minimum pulse width of the encoded IR_TXD pulse (and the IR_RCV pulse). As per the IrDA
specifications, the minimum pulse width of the IR_TXD and IR_RCV pulses should be 3 * (1/1.8432 MHz) or 1.63 s. The minimum
pulse width specified for the HSDL-7000 is 250 ns, which is within IrDA specification. Under normal circumstances, the pulse width
should not be less than 1.63 s.
