2008BVLF

SMPTE TIME CODE RECEIVER/
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.
