COMPANY CONFIDENTIAL PI3EQXDP1201 3.3V, 4-Ch DisplayPort 1.2 Redriver with Aux Listener/AutoTest mode Features Description ÎÎCompliant with VESA DisplayPort 1.2 specification PI3EQXDP1201 provides the ability to reduce signal jitter by transmission line effects to enable longer cable length on the 5.4Gbps DisplayPort1.2 signals. Integrated AUX decoder can support Displayport link training. It can decipher the link training message and automatically configure Displayport differential signal outputs with the best pre-emphasis and output swing level settings. Input Equalization, Output level swing and pre-emphasis are controlled by either Aux link snooping or pin configuration. Decoding of the Aux command happens during link training. Built-in Sync Request Auto Test mode enables users to complete DisplayPort link status through Aux channels in minutes. PI3EQXDP1201 is intended for use in any systems, DP signal compliance is required, including notebook PC and docking stations, Graphic cards and digital video systems. for HBR2, HBR, RBR rate (5.4/2.7/1.62Gbps) ÎÎDual mode DisplayPort Outputs by providing DDC signals across the Aux sink pin ÎÎBuilt-in Aux interception circuit only listen to the link training, but does not affect link training ÎÎSink Request Auto Test Mode through Aux Channels ÎÎDynamic EQ through Aux configuration register programming for deterministic jitter reduction ÎÎCable Detection pins, toggle between DP and TMDS mode ÎÎAutomatic power down state when HPD signal is low ÎÎLow insertion loss across the Aux signal path ÎÎDedicated pin control mode for Equalization setting control ÎÎInternally Biased AC coupled in Aux channel ÎÎSingle Power Supply: 3.3V ÎÎIntegrated ESD protection ÎÎPackage : 48-pin TQFN, 7mm x 7mm Applications ÎÎNotebook and Dock station ÎÎPC system boards ÎÎDigital video systems Typical Application Functional Block Diagram OUT0P/N IN0P/N IN1P/N 5-10” trace length recommended DP Mux DP Redriver IN2P/N Connector DP++ Source Device IN3P/N HPD_SRC ENABLE CNTRL CAD_SRC AUX_SRC SCL/SDA 15-0021 Equalizer Pre-Emphasis 1 OUT1P/N OUT2P/N OUT3P/N Control Logic & Configuration Registers Aux Listener, Aux Pass-through, DDC pass-through Blocks HPD_SNK CAD_SNK AUX_SNK www.pericom.com02/27/15 COMPANY CONFIDENTIAL PI3EQXDP1201 3.3V, 4-Ch DisplayPort 1.2 Redriver with AUX Listener/AutoTest mode 15-0021 SCL_DDC V3P3 GND AUX_SRCP AUX_SRCN AUX_SNKP AUX_SNKN ENABLE V3P3 33 32 31 29 28 27 26 25 30 SDA_DDC 34 35 V3P3 AUTO_EQ 36 Package Pinout DNC 37 24 GND IN0P 38 23 OUT0P IN0N EQ 39 22 OUT0N 40 21 DNC IN1P 41 20 OUT1P IN1N 42 19 OUT1N DNC 43 18 GND IN2P 44 17 OUT2P IN2N OC_0 45 16 OUT2N 46 15 DNC IN3P 47 14 OUT3P IN3N 48 13 OUT3N 1 2 3 4 5 6 7 8 9 10 11 12 V3P3 DNC OC_1 OP_0 OP_1 V3P3 CNTRL CAD_SRC HPD_SRC CAD_SNK HPD_SNK V3P3 GND 2 www.pericom.com02/27/15 COMPANY CONFIDENTIAL PI3EQXDP1201 3.3V, 4-Ch DisplayPort 1.2 Redriver with AUX Listener/AutoTest mode Pin Description Pin # Pin Name Pin Type Description 1 V3P3 Power 3.3V +/10% Power rail 2 DNC NC 3 OC_1 Input Swing control bit 1.

After HPD IRQ event and DP source read 00201h AUX register and if bit 1 is high, the DP source will enter a Sink request test mode and initiate a sequence of AUX read request cycle. During the read cycle, data matching the following registers address are stored in the listener. Intelligent Power Management Pericom’s block based design and intelligent detection scheme allow portions, or all of the IC, to be disabled for power savings. For example, in DP mode, if only one or two lanes are active, the other lanes will be automatically powered off. If there is no input video signal the entire IC will be powered down. If there is no monitor detected, Pericom’s PI3EQXDP1201 can also automatically power down the IC. This intelligent power management concept not only saves system power, but also stops the device from outputting useless data or noise when no signal is present at the input of the IC. The power-down mode can also be entered using hard pin ENABLE, or through DPCD register (AUX link training) 00206hADJUST_REQUEST_LANE0_1 00207hADJUST_REQUEST_LANE2_3 00218h Test Request 00219h Test link rate 00220h Test Lane count DisplayPort AUX Listener After the read request cycle, the DP source will write 1 to Bit 0 register 00260h if the DP source enters sink request mode, or 1 to Bit 1 of register 00260h if the source declined the sink test request. The data stored in registers 002xx above will override the value set in 00101h to 00106h registers when the sink entered the Sink Test mode. PI3EQXDP1201 integrates an AUX listener(decoder), which enables the device to receive and decipher all AUX link training data and use this extracted information for its own configuration. The intercepted DPCD data is used to adjust the active lane count, output swing level, output pre-emphasis level, and to manage the device’s D3 power saving state. Sink Test Request Acknowledgement AUX Listener Specification 00260h mode Buffer configuration outputs DP AUX listener will support Native AUX CH Syntax. Mapping of I2C onto AUX CH Syntax is not supported. AUX listener monitors AUX channel from requester and replier for transactions and stored AUX command from requester and reply command from sinks that are related to the link settings. AUX listener recovered the clock from AUX data input by cycle counting the synchronization pulse at the beginning of the AUX cycle. In a AUX write request cycle, the AUX address compare the addresses with the following registers’ address, data is extracted and stored into the respective registers when the addresses matches. These registers are set during link training sequence following hot plug detection. xxxxxx00b No action 00100 : 00106h xxxxxx01b Sink Test mode 00206h,00207h,00219h,00220h Override 00100,1,3,4,5,6h register settings xxxxxx10b Sink test mode 00100h : 00106h declined xxxxxx11b Not Legal code 00100h : 00106h 00100h Data Rate Register 00101hLANE_COUNT_SET 00103hTRAINING_LANE0_SET 00104hTRAINING_LANE1_SET 00105hTRAINING_LANE2_SET 00106hTRAINING_LANE3_SET 00260h 15-0021 Sink Test request response 6 www.pericom.com02/27/15 COMPANY CONFIDENTIAL PI3EQXDP1201 3.3V, 4-Ch DisplayPort 1.2 Redriver with AUX Listener/AutoTest mode A complete two way AUX transaction is defined as one of the following 1.

At Power on Reset state, low power state 1 and low power state 2, all outputs are HiZ, equalizer is powered down, HPD _SRC is HiZ. At Lower Power Mode State 2, if HPD_SNK is asserted, it will turn output signals active. If output port is active and HPD_SNK = 0, then it will go to a debounce timer and wait for 300ms, if HPD_SNK is still =0, the controller will return to Low Power mode wait state 2. If HPD_SNK is 1 then the controller will return to output port active state. HPD_SNK will pass through HPD _SRC.
