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.
