The PS8407A is a low power HDMI™ repeater / retimer that removes jitter and fully supports HDMI 1.4b by supporting up to 300MHz TMDS™ clock rate. The device integrates a jitter tolerant TMDS receiver and a jitter cleaning TMDS transmitter for HDMI repeater applications. It removes both the data and clock jitter and the timing skews from the TMDS input to deliver a compliant and very low jitter HDMI output.
The PS8407A is ideal for Source, Sink and repeater device applications where jitter attenuation is needed. Such requirement might exist in a Source to remove Tx jitter and/or induced media (transmission path) jitter in order to meet HDMI output jitter requirements, especially at higher TMDS clock rates. It can also be used within a switch or Sink as a repeater function to improve signal integrity. Signal integrity can be further optimized through the use of the PS8407A’s programmable input equalization and output pre-emphasis controls.
The PS8407A also includes the VESA Dual-Mode DisplayPort Type 2 cable adaptor DDC registers. This enables the GPU to change devices settings and identify capability, using standard Dual-Mode DisplayPort Type 2 adaptor drivers. The PS8407A is not designed for Type 2 cable adaptors since it does not include the required I2C-over-AUX transaction support. For Type 2 cable adaptor applications refer to the PS8402A.
The PS8407A can accept either an AC or DC coupled input signal.
