It incorporates a selectable 5th order Butterworth anti-aliasing / DAC – AC-Coupled with Bias reconstruction filter to eliminate data converter – DC-Coupled with 250-mV Input Shift images. The 9-MHz is a perfect choice for SDTV – DC-Coupled video including composite, S-Video™, and 480i/576i • 2:1 Input MUX Allows Multiple Input Sources Y'P'BP'R or G'B'R' (R'G'B') video. The 16-MHz filter is ideal for EDTV 480p/576p Y'P'BP'R, G'B'R', and VGA • External Gain Control Range From signals. The 35-MHz filter is useful for HDTV 0 dB to 14 dB 720p/1080i Y'P'BP'R, G'B'R', and SVGA/XGA signals. • 2.7-V to 5-V Single Supply Operation For 1080p or SXGA/UXGA signals, the filter can be • Low 16.2-mA (3.3 V) Total Quiescent Current bypassed allowing a 150-MHz bandwidth, 300-V/ μs amplifier to buffer the signal. • Disable (< 1 μA) and Mute Control Functions Each channel of the THS7353 is individually I2C • Rail-to-Rail Output: configurable for all functions which makes it flexible – Allows AC or DC Output Coupling for any application. Its rail-to-rail output stage allows • Low Differential Gain/Phase of 0.15%/0.3° for both ac and dc coupling applications. The externally controlled gain adjust pin allows for fine tuning of the gain such as line driving, compensating for cable losses, or Sin-X/X compensation.
