THE PROOF IS ON THE INSIDE AND OUT
After you have reviewed the PFS-875, look inside, your will be pleased to know we are using a BGA FPGA and it
is made in the USA. This device provides many features to be crammed into one RU chassis
OK - the PFS-875 is envisioned as a product of the future. The unit is comprised of a 4 field TBC/frame
synchronizer with full transcoding on the analog inputs and a user configurable set of triple analog outputs as well
as SDI input and output. All processing is completely digital and includes a full proc amp as well as adjustable
output levels and timing.
The PFS-875 is designed as a standalone gen-lock-able frame sync with a variety of both analog and digital inputs
and outputs. The developmental was aimed to produce a broadcast quality unit as an initial offering, and then to
potentially use portions of this new platform in a variety of new products (modules for existing card frame products,
digital proc amp, etc.).
The PFS-875 provides dual standard composite and SDI timebase correction and synchronization to an external
reference. The unit will decode multiple composite standards (NTSC, NTSC-J, PAL-B,G,H,I,N). All analog inputs
are sampled with 10 bit resolution and decoded using a 3 line digital comb filter.

Audio Embedding & De-embedding
There are four video input and output formats supported
by the PFS-875; Composite Video, Component Analog
Video (YUV), Y/C (S-VHS) and SDI. The component
analog video input is YUV (SMPTE), and component
output is YUV (SMPTE/Beta-cam). The analog output
is on three BNC connectors which can be programmed
from the front panel to output all 3 composite, or
composite and Y/C, YUV SMPTE, or YUV BETA.
The PFS-875 provides dual standard composite and
SDI correction and synchronization to an external
analog reference. The synchronizer decodes multiple
composite standards (NTSC, PAL). All analog inputs
are sampled with 12-bit resolution and decoded using
a 5 line adaptive comb filter. It also has a built-in color
bar or black burst generator. The PFS-875 can also
synchronize non TBC signals from VHS tapes.
When input video is lost, the synchronizer freezes the
video or generates a test pattern. There are three ways
to freeze the video, freeze to the last known good
frame, field 1, or field 2. The test patterns that can be
generated are SMPTE color bar for NTSC, 75 % color
bar for PAL, and black burst for both.
PFS-875 has the feature to embed and de-embed two
channels of stereo AES audio. The De-embedded AES
audio is output through 2 separate BNCs on the rear
panel. Similarly, AES input for embedding can be input
through 2 separate BNCs. It has the feature of
choosing to embed the de-embedded audio and move
the audio to another group or channels. It also has the
feature of delaying the audio to match the video delay.
One of the new developments to be included in this
product is an all-digital composite NTSC/PAL encoder.
The encoding process allows for an image quality
superior to any of the off-the-shelf encoder ICs
available on the market at present, and also gives a
superior gen-lock capability. The encoder process
implements 12-bit outputs.
The PFS-875 has the feature of three built-in
processing amplifiers. One “proc. amp.” is for the
analog output allowing you to control luma,
chrominance, Sync, Burst, and Set-up levels along with
a black clip and hue phase adjustment. The second
“proc. amp.” is for the SDI output allowing you to control
luma, chrominance and set-up levels along with a black
clip. The third “proc. amp.” is for the analog input
affecting both analog and SDI outputs, which allows you
to control the luma and chrominance levels along with
hue phase adjustments.
