Superior Performance
The CX25836/7 high quality video decoder offers superior
performance through advances in technology, integration,
and patented intellectual property.
For example, a new and improved arbitrary horizontal and
vertical scaler, from full resolution down to an 8:1 ratio (icon
size), has been implemented using a polyphase interpolation
filter. This maintains a high-quality scaled image that preserves
the detail and aspect ratio of the source material. Scaling can be
accomplished in both ITU-R BT.656 and square formats.
Additionally, new advances in clamping, Automatic Gain Control
(AGC), and DC restore circuitry allow for faster lock times upon
channel change and improved signal reconstruction abilities to
improve the video decode process. The CX25836/7 is offered
in a compact 64-pin 7x7 mm TQFP and operates off of a single
3.3 V regulator.
Moreover, the surrounding Bill of Materials (BOM) has been
integrated and optimized for performance and overall cost
effectiveness. Together, small package and integration yield
high performance in a small package. To maximize the customer’s
flexibility and minimize the board space by eliminating multiple
foot print options, the CX25837 is also offered in an 80-pin
12x12 mm device, which is pin-for-pin compatible with the
CX25840/1/2/3 broadcast A/V decoder. Broadcast audio can be
added by a mere device change. Finally, the CX25836/7 has multiple
power-down modes to address low-power applications and power
budget-sensitive designs. The video decoder is designed on
the latest sub-micron process, which reduces the overall power
consumption through the advantages of reduced geometries.
