Integrated Circuit Systems, Inc. ICS2008B SMPTE Time Code Receiver/Generator The ICS2008B, SMPTE Time Code Receiver / Generator chip, is a VLSI device designed in a low power CMOS process. This device provides the timing coordination for Multimedia sight and sound events. Although it is aimed at a PC Multimedia environment, the ICS2008B is easily integrated into products requiring SMPTE time code generation and/or reception in LTC Longitudinal Time Code and/or VITC Vertical Interval Time Code formats and MTC MIDI Time Code translation. Taking its input from composite video, S-Video, or an audio track, the ICS2008B can read SMPTE time code in VITC and LTC formats. Time code output formats are LTC and VITC. All are available simultaneously. A UART is provided for the user to support MTC or tape transport control. The processor interface is compatible with the IBM PC and ISA bus compatible computers and is easily interfaced to other processors and micro-controllers. The ICS2008B is an improved version of the ICS2008, with additional features and capabilities.

If AC coupling is attempted in these cases, then great care must be taken that the voltage at the input pin does not go below ground nor be allowed to settle near the threshold value. In such cases, it is recommended that the input pin in question be observed in operation with a high-impedance scope probe. In the case of large voltage swing inputs, the ICS2008B input pin can easily be driven below ground. This is possible because the voltage at the pin will swing around the internally generated bias point. Driving the input pin below ground should never be allowed and can potentially damage the device. In the case of a large input swing, a series resistor can be placed between the coupling capacitor and the input pin to divide down the input voltage and reduce the swing at the input pin. In the case of low frequency signals, the coupling capacitor can become fully charged which will allow the input slew to close to its threshold value, causing any noise to falsely trigger the input. Low duty cycle inputs can have an effect similar to low frequency. A larger coupling capacitor may be required. The case of a low frequency, large amplitude input is especially dangerous because the voltage swing at the input pin is increased by the same amount that the capacitor has charged. As an example of the measures that may need to be taken, a 5V, 30 Hz, 50% duty cycle signal on the Click input can be safely AC coupled to the Click pin by using a 1µF coupling capacitor and a 100K ohm series resistor. The large time constant prevents the capacitor from becoming fully charged and the series resistor, combined with the internal resistor, divides down the input voltage to an acceptable swing so that the input pin is never driven below ground.

ICS2008B Errata

Figure 8 “Self Biased Inputs” Diagram on page 15 a VDD/2 should be VDD/3 b 5K should be 35K

Add the following notes called “AC Coupling of Internally-Biased Inputs” after “Self Biased Inputs” section on page

AC coupling is not recommended when the input is of large voltage swing and/or of low frequency. If AC coupling is attempted in these cases, then great care must be taken that the voltage at the input pin does not go below ground nor be allowed to settle near the threshold value. In such cases, it is recommended that the input pin in question be observed in operation with a high-impedance scope probe.

In the case of large voltage swing inputs, the ICS2008B input pin can easily be driven below ground. This is possible because the voltage at the pin will swing around the internally generated bias point. Driving the input pin below ground should never be allowed and can potentially damage the device. In the case of a large input swing, a series resistor can be placed between the coupling capacitor and the input pin to divide down the input voltage and reduce the swing at the input pin.

In the case of low frequency signals, the coupling capacitor can become fully charged which will allow the input slew to close to its threshold value, causing any noise to falsely trigger the input. Low duty cycle inputs can have an effect similar to low frequency. A larger coupling capacitor may be required. The case of a low frequency, large amplitude input is especially dangerous because the voltage swing at the input pin is increased by the same amount that the capacitor has charged.

As an example of the measures that may need to be taken, a 5V, 30 Hz, 50% duty cycle signal on the Click input can be safely AC coupled to the Click pin by using a 1µF coupling capacitor and a 100K ohm series resistor.
