Introduction
The R5CE SDI monitoring distribution amplifier provides four equalized, re-
clocked and separately buffered serial digital outputs, plus four analog
monitoring outputs. One analog output is NTSC/PAL. The other three analog
outputs are configurable to a wide variety of formats, including composite,
composite and Y/C (S Video), or component—including SMPTE/N10 (YUV),
RGB, and true Betacam levels.
In operation, the R5CE automatically configures to 525 or 625 line component
digital inputs and then outputs analog NTSC (525, line input), PAL (625 line
input) and component analog as determined by DIP switch settings. A PLL jitter
filter/memory reduces the effects of SDI jitter on the analog outputs. Another
exclusive feature of the R5CE is a 10- to 8-bit dithering circuit that removes
contouring in the analog outputs.
The R5CE encodes the full dynamic range of input component video—values
below black and above white are not clipped. In the NTSC mode, the 7.5 IRE
pedestal can be disabled by an external DIP switch selection. The R5CE also
features a PLL filter, which reduces SDI input jitter for stable composite or
component analog outputs.
