The TMDS181IRGZT is a 6Gbps HDMI retimer in 48 pin VQFN package. The TMDS181I is a digital video interface or high-definition multimedia interface (HDMI) retimer. The TMDS181I supports four TMDS channels, audio return channel (SPDIF_IN/ARC_OUT) and digital display control (DDC) interfaces. It supports signalling rates up to 6Gbps to allow for the highest resolutions of 4k2k60p 24bits per pixel and up to WUXGA 16bit colour depth or 1080p with higher refresh rates. It can be configured to support the HDMI2.0a standard. It automatically configures itself as a redriver at low data rate (<1Gbps) or as a retimer above this data rate. Redriver mode supports HDMI1.4b with data rates up to 3.4Gbps. It supports dual power supply rails of 1.2V on VDD and 3.3V on VCC for power reduction. It supports fixed receive EQ gain or adaptive receive EQ control by I2C or pin strap to compensate for different lengths input cable or board traces.
● HDMI input port to output port with CDR supporting up to 6Gbps data rates
● Compatible with HDMI electrical parameters up to 6Gbps in retimer mode
● Retimes input stream to compensate for random jitter
● Adaptive receiver equalizer or programmable fixed equalizer
● I2C and pin strap programmable
● Inter pair skew compensation of 5+bits
● Single ended mode ARC support
● Link debug tools including eye diagram after the receiver equalizer
● Electrostatic discharge is 2KV (human body model)
● Industrial temperature range from -40°C to 85°C
●It has been limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
