THS7314 3-Channel SDTV Video Amp w/5th Order Filters and 6-dB Gain
Fabricated using the Silicon-Germanium (SiGe) BiCom-III process, the THS7314 is a low power single-supply 3-V to 5-V 3-channel integrated video buffer. It incorporates a 5th-order Butterworth filter which is useful as a DAC reconstruction filter or an ADC anti-aliasing filter. The 8.5-MHz filter is a perfect choice for SDTV video which includes Composite (CVBS), S-Video, Y'U'V', G'B'R' (R'G'B'), and Y'P'BP'R 480i/576i.
As part of the THS7314 flexibility, the input can be configured for ac or dc coupled inputs. The 285-mV output level shift to allow 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 CVBS, Y', and G'B'R' signals with sync
