Supporting Up to 6 Gbps Data Rates The TMDS181x supports four TMDS channels, audio Compatible With HDMI Electrical Parameters return channel (SPDIF IN/ARC OUT), and digital Up to 6 Gbps in Retimer Mode display control (DDC) interfaces. The TMDS181x Support 4k2k60p and Up to WUXGA 16-Bit Color supports signaling rates up to 6 Gbps to allow for the highest resolutions of 4k2k60p 24 bits per pixel and Depth or 1080p With Higher Refresh Rates up to WUXGA 16-bit color depth or 1080p with higher Retimes Input Stream to Compensate for Random refresh rates. The TMDS181x can be configured to Jitter support the HDMI2.0a standard. The TMDS181x Adaptive Receiver Equalizer or Programmable automatically configures itself as a redriver at low Fixed Equalizer data rate (<1.0 Gbps) or as a retimer above this data 2 rate. Redriver mode supports HDMI1.4b with data I C and Pin Strap Programmable rates up to 3.4 Gbps Inter-Pair Skew Compensation of 5+ Bits The TMDS181x supports dual power supply rails of Single-Ended Mode ARC Support 1.2 V on V and 3.3 V on V for power reduction. DD CC Link Debug Tools Including Eye Diagram After the Several methods of power management are RX Equalizer implemented to reduce overall power consumption. 48-Pin 7-mm 7-mm 0.5-mm Pitch VQFN TMDS181x supports fixed receive EQ gain or 2 Package adaptive receive EQ control by I C or pin strap to compensate for different lengths input cable or board Extended Commercial Temperature Support 0C traces. to 85C (TMDS181) Industrial Temperature Support: 40C to 85C (1) Device Information (TMDS181I) PART NUMBER PACKAGE BODY SIZE (NOM) TMDS181 2 Applications VQFN (48) 7.00 mm 7.00 mm TMDS181I Digital TV (1) For all available packages, see the orderable addendum at Digital Projector the end of the data sheet.
