STDVE001A

STDVE001A Adaptive single 3.4 Gbps TMDS/HDMI signal equalizer Preliminary Data Features ■ Compatible with the high-definition multimedia interface (HDMI) v1.3 digital interface ■ Conforms to the transition minimized differential signaling (TMDS) voltage standard on input and output channels ■ 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 cables lengths up to 25 m ■ Single supply VCC: 3.135 to 3.465 V ■ ESD: ±8 KV contact 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 of all the channels ■ Equalizer regenerates the incoming attenuated TMDS signal ■ Buffer drives the TMDS outputs over long PCB track lengths ■ Low output skew and jitter ■ Tight input thresholds reduce bit error rates ■ On-chip selectable 50 Ω input termination ■ Low ground bounce ■ Data and control inputs provide undershoot clamp diode ■ Evaluation kit is available Table 1. Device summary Order code Operating temperature STDVE001ABTR STDVE001AQTR -40°C to 85°C -40°C to 85°C TQFP48 QFN48 Description The STDVE001A integrates a 4-channel 3.4 Gbps TMDS equalizer. High-speed data paths and flowthrough pinout minimize the internal device jitter and simplify the board layout. The equalizer overcomes the intersymbol in...
