1 www.pericom.com ps9058 11/30/09 PI3HDMI2410 description pericom semiconductors pi3hdmi series of switch circuits are targeted for high-resolution video networks that are based on dvi/hdmi? standards. th e PI3HDMI2410 is a 4-to-1 hdmi mux/demux signal switch. it is designed for low bit-to-bit skew and high channel-to-channel noise isolation. th e maximum data rate support is up to 5gbps which can meet hdmi 1.3a stan- dard and support the resolution requirement of next generation hdtv and pc graphics. PI3HDMI2410 is designed specifi cally for atc-sink require- ments. all switch control settings are through i 2 c bus to provide fl exible design and reducing peripheral components. selectable active signal buff er for ddc bus can optimize the bi-directional data transmission for long trace or cable applications. all input pins are protected with pericoms esd protection circuits supporting esd damage as high as 8kv contact per iec61000-4-2 level 4 specifi cation. features ?? 4:1 hdmi switch mux ?? non-blocking eq path for ideal eq control in main receiver chipset ?? -3db bandwidth up to 5gbps to support hdmi 1.3a (16-bit color depth per channel) ?? hdmi 1.4 data rate ready ?? ddc active signal buff er or passive switch selectable ?? i 2 c register control for switch confi guration ?? automatic hdcp reset circuitry for quick communication when switching from one port to another ?? hpd polarity control and signal trigger through i 2 c register setting ?? connector plug-in detection and interrupt flag setting ?? selectable hpd 5v signal level shift er with open drain output stage or output buff er ?? 3.3v power supply and standby power supply ?? tmds output enable control ?? low power consumption to support energy star compliance ?? esd protection on all i/o pins ? 8kv contact per iec61000-4-2, level 4 ?? packaging (pb-free & green available): ? 80-contact lqfp 4-port hdmi? signal switch with i 2 c control 09-0099

9 www.pericom.com ps9058 11/30/09 PI3HDMI2410 4-port hdmi? signal switch with i 2 c control bus transactions data transfers follow the format shown in fig.1. aft er the start condition (s), a slave address is sent. th is address is 7 bits long followed by an eighth bit which is a data direction bit (r/w) - a zero indicates a transmission (write), a one indicates a request for data (read). a data transfer is al- ways terminated by a stop condition (p) generated by the master. however, if a master still wishes to communicate on the bus, it can generate a repeated start condition (sr) and address another slave without fi rst generating a stop condition. various combinations of read/write formats are then pos- sible within such a transfer. figure 1: a complete data transfer 09-0099
