STV6418
Audio/video switch and 6-channel SD/PS/HD video filter
Data brief
Features
■ I2C bus control
■ Auto startup mode: low power consumption
■ Video section:
– Three CVBS inputs, two CVBS outputs
– Three Y/C inputs, three Y/C outputs
– Switchable 8 MHz, 15 MHz or 30 MHz low-
pass filters (LPF) on six inputs for standard
definition, progressive scan and interleaved
high definition, plus bypass (60 MHz) for
progressive high definition
– Gain of 6 dB on all CVBS/Y and C outputs
– Integrated 150-Ω buffers
– Two RGB/one FB inputs, one high
impedance RGB/FB output with 6-dB
adjustable gain (from +3 dB to +9 dB)
– Two YPrPb inputs, one YPrPb/RGB HD
output
– AC or DC-coupled video outputs
– Two slow blanking inputs/outputs
– Bottom clamp on all CVBS/Y and RGB
inputs, average clamp on C inputs,
synchronized clamp on PrPb inputs
– Bi-directional control for VCR R/C output
and for TV B output
– AC-coupled inputs and AC- or DC-coupled
inputs for video signal from encoder with
internal clamp and bias
– Video detection block in low power auto
startup mode
– Video muting on all outputs
■ Audio section:
– Three stereo inputs, two stereo outputs
TQFP48 (7 × 7 × 1 mm3) EPD
(48-pin thin quad flat pack with exposed pad down)
– Stereo-to-mono sound capability
– Differential or single-ended audio input
– Selectable gain of 0, 6 or 9 dB on one
stereo input
– Full-range volume control with soft control
– Audio muting on all outputs
Applications
■ Set-top boxes (IP, cable, satellite, terrestrial)
■ Integrated digital TV plug-in
■ Blu-ray and DVD players
Description
The STV6418 is a highly integrated I2C bus-
controlled audio and video switch matrix,
optimized for use in digital set-top box
applications. It provides all the audio and video
routings required in a full two-SCART set-top box
design.
The STV6418 provides fully integrated solutions
for filtering and buffering both SD and HD signals.
