STDVE103A

STDVE103A Adaptive 3.4 Gbps 3:1 TMDS/HDMI signal equalizer Preliminary Data Features ■ Digital video signal equalizer with 3:1 HDMI switch ■ Compatible with the high-definition multimedia interface (HDMI) v1.3 digital interface ■ 340 MHz maximum clock speed operation supports all video formats with deep color at maximum refresh rates ■ 3.4 Gbps data rate per channel ■ Fully automatic adaptive equalizer for cable lengths up to 25 m ■ Selectable 50 Ω input termination to VCC: 3.135 to 3.465 V ■ Low speed control lines supply to VDD : 5 V (typ) ■ ESD HBM model : > ±5 KV for all I/Os ■ Integrated open-drain I2C buffer for display data channel (DDC) ■ 5.3 V tolerant DDC and HPD I/Os ■ Lock-up free operation of I2C bus ■ 0 to 400 kHz clock frequency for I2C bus ■ Low capacitance TMDS channels ■ Equalizer for signal regeneration ■ Low output skew and jitter Applications ■ Advanced TVs supporting the HDMI/DVI standard ■ Front projectors, LCD TVs and PDPs ■ Monitors and notebooks ■ Set-top box and DVD players TQFP64 Description The STDVE103A integrates a 4-channel 3.4 Gbps TMDS equalizer and a 3:1 switch to select one of the three HDMI ports. The high-speed data paths and flow-through pinout minimize the internal device jitter and simplify the board layout. The equalizer overcomes the jitter effects from lossy cables. The buffer/driver on the output can drive the TMDS output signals over long distances. Also, STDVE103A integrates the 50 W termination resistor on all the input chann...
