frequency of 527 kHz.
9) ASK Receive Choices - valid incoming frequency range (with RATS = 0 and MD = 5) is 431 kHz to
609 kHz.
10) RATS register control of receive data frequency window period is now:
T(min) ~= [(2*MD)+3+RATS]*135ns
T(max) ~= [(2*MD)+3+(6*(RATS+1))]*135ns
11) Clarification: the IrDA/HP-SIR baud rate can be as low as 1200 bps.
12) Specifications in the following tables replace those found in the JUN ’94 CS8130 data sheet
(DS134PP2).

Notes: 1. Power supply current specifications are with the supply at 3.0 V. For approximate consumption at
+5.0 V, multiply the above currents by 1.667.
2. Oscillator in low power mode; does not include LED current. Subtract oscillator current if using an
external clock to run the CS8130.
3. Floating digital inputs will not cause the power supply to increase beyond the specification.
4. Does not include LED current, does include oscillator current in low power mode.
