High-density FIFO for camera control unit and base station

13-02-2015 | Cypress | Design Applications

Cypress Semiconductor has announced that Ikegami Tsushinki Corp., the
world's leading manufacturer of advanced high-definition (HD) cameras and
production equipment, has selected Cypress's high-density First-In,
First-Out (FIFO) memory for its 3G-ready fibre transmission camera control
unit and base station. Ikegami chose Cypress's CYF0072 SRAM-based
high-density FIFO for its ability to buffer HD video frames with enhanced
signal integrity.

Cypress's 72-Mb video frame buffer solution operates as a FIFO with
independent read and write ports for fast data transfer. The solution is an
effective alternative to standard DRAM-based FIFO memories because of its
high density, lower power consumption and heat dissipation, smaller
footprint and lower cost. The simple SRAM-based interface reduces
implementation and debugging effort, improves time-to-market, and reduces
engineering costs.

Ikegami's CCU-980 camera control unit and BS-98 base station are used with
the company's full digital 3G HDTV portable camera system for live
television broadcasts. The systems leverage the Cypress FIFO solution to
buffer HD images for progressive-to-interlaced and interlaced-to-progressive
conversion, perform frame synchronization with variable delay buffering, and
enable sophisticated filtering operations via programmable flags and
write-mask and read-skip features.

"We are pleased that Ikegami has selected our 72-Mb FIFO for their newest
3G-enabled camera control unit and base station," said Sunil Thamaran,
senior business unit director for specialty memories, Cypress.
"High-definition video is a booming market and our SRAM-based FIFOs provide
an ideal solution to ensure signal integrity for these HD broadcast
applications, positioning us for continued success in the video imaging

Cypress's 72-Mb FIFO delivers enhanced signal integrity and operates at
frequencies up to 133MHz with throughput up to 4.8Gbps - commonly required
for buffering video frames. With the ability to operate in any system that
needs buffering at high speeds across different clock domains, the video
frame buffers are ideal for a wide range of video and image processing
applications, including picture-in-picture and interlacing in HD cameras,
scan rate conversion in broadcast equipment, image scanning and enhancement
in medical equipment, and radar and sonar defence systems.
