TPF133A

Low Power, 3-channel Video Filter for HD Video

Description

Features

TPF133A is a specially designed for consumer applications,

high-performance, low-cost video reconstruction filter, it

combine excellent video performance and low power

consumption perfectly. It incorporates three high-definition

(HD) filter channels. All filters feature sixth-order Butterworth

characteristics that are useful as digital-to-analog converter

(DAC) reconstruction filters or as analog-to-digital converter

(ADC) anti-aliasing filters. The HD filters can be bypassed to

support filters. The HD filters can be bypassed to support

1080p60 video or up to quad extended graphics array

(QXGA) RGB video.

⚫

3-HDTV Video Filter Support Y'Pb'Pr'-1080i/720p,

R'G'B' or VGA/SVGA/XGA

Optimized 6^th-order Butterworth Video reconstruction

⚫

filter：

HD Channel: -3dB ≥ 36MHz

Support Multiple Input Biasing:

⚫

Provide 80-mV Level-Shift when DC-Coupled

Transparent Input Clamping when AC-Coupled

Support External DC Biasing when AC-Coupled

⚫

Very Low Quiescent Current: 11.7 mA(at 3.3V, Typical)

6dB Gain(2V/V), Rail TO Rail Output

AC- or DC-Coupled Output Driving Dual Video Loads

(75Ω)

As part of the TP133A flexibility, the input can be configured

for ac- or dc-coupled inputs. The 84-mV output level shift

allows for a full sync dynamic range at the output with 0-V

input. The ac-coupled modes include a transparent sync-tip

clamp option for Y', and G'B'R' signals. AC- coupled biasing

for C'/P'B/P'R channels can easily be achieved by adding an

external resistor to VS+.

⚫

Wide Power Supply: +3.0V to +5.5V Single Supply

Robust ESD Protection:

Robust 8kV – HBM and 2kV – CDM ESD Rating

The TP133A rail-to-rail output stage with 6-dB gain allows for

both ac and dc line driving. The ability to drive two lines, or

75-Ω loads, allows for maximum flexibility as a video line

driver. The 27.6-mA total quiescent current at 3.3 V makes it

an excellent choice for power-sensitive video applications.
