AD8197A datasheet

Description :

The AD8197A is an HDMI™/DVI switch featuring equalized TMDS® inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. Outputs can be set to a high impedance state to reduce the power dissipation and/or to allow the construction of larger arrays using the wire-OR technique. The AD8197A is provided in a 100-lead LQFP, Pb-free, surface mount package, specified to operate over the −40°C to +85°C temperature range.

4 inputs, 1 output HDMI/DVI link
Enables HDMI 1.3-compliant receiver
Pin-to-pin compatible with the AD8191A
4 TMDS channels per link
Supports 250 Mbps to 2.25 Gbps data rates
Supports 25 MHz to 225 MHz pixel clocks
Equalized inputs for operation with long HDMI cables
(20 meters at 2.25 Gbps)
Fully buffered unidirectional inputs/outputs
Globally switchable, 50 Ω on-chip terminations
Pre-emphasized outputs
Low added jitter
Single-supply operation (3.3 V)
4 auxiliary channels per link
Bidirectional unbuffered inputs/outputs
Flexible supply operation (3.3 V to 5 V)
HDCP standard compatible
Allows switching of DDC bus and 2 additional signals
Output disable feature
Reduced power dissipation
Removable output termination
Allows building of larger arrays
2 AD8197A devices support HDMI/DVI dual-link
Standards compatible: HDMI receiver, HDCP, DVI
Serial (I2C slave) and parallel control interface
100-lead, 14 mm × 14 mm LQFP, Pb-free package

Multiple input displays
A/V receivers
Set-top boxes
Advanced television (HDTV) sets
