New UART frequency of 38.4 K for tape transport control
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.
