PTN3816 DisplayPort 20Gbps 4-lane linear redriver Rev. 1.0 7 June 2021 Product data sheet 1 General description PTN3816 is a high performance 20 Gbps per lane, 4-lane DisplayPort linear redriver for DisplayPort upstream (DP source side) and downstream (DP Sink side) applications. It is used to improve high speed signal quality in DisplayPort interfaces in various platforms and applications. The device provides pin programmable receive equalization, output linearity control to improve signal integrity and enable channel extension by reducing Inter-Symbol Interference (ISI). This IC also implements AUX snooping to monitor the AUX signals to optimally configure the link and achieve power saving and SI performance. PTN3816 has control pins for application specific configurability. These pins can either be strapped appropriately on the PCB or connected to a microcontrollers GPIO pins. PTN3816 does not require any I2C software configuration. PTN3816 is powered from 1.8 V supply. It is available in a small high performance HWFLGA36 package with 2.1 mm x 6.0 mm x 0.6 mm size and 0.4 mm pitch. 2 Features and benefits Implements DisplayPort linear redriver that can operate for various link rates - 1.62 Gbps (RBR), 2.7 Gbps (HBR), 5.4 Gbps (HBR2) 8.1 Gbps (HBR3), 10, 13.5 and 20 Gbps Supports configurable number of lanes: 1, 2 and 4 DP AUX monitoring for link configuration and power management Implements HPD for deep power saving Configurable Rx Equalizer gain Configurable output swing linearity control High Speed redriver path supports DP++ mode that targets DP to HDMI interface use Supports maximum voltage limit (V ) to align to the latest system platform voltage jump capabilities Integrated termination resistors provide impedance matching on transmit and receive sides Good linearity over the frequency band (50 MHz to 10.3 GHz) and voltage dynamic range Excellent Differential return loss performance: < -16 dB up to 10.3 GHz Flow-through pin-out to ease PCB layout and minimize crosstalk effects Low active current consumption for output linearity control setting of 950 mVppd 1-lane DP : 62 mA (typ) 2-lane DP : 125 mA (typ) 4-lane DP : 250 mA (typ)NXP Semiconductors PTN3816 DisplayPort 20Gbps 4-lane linear redriver Powersaving state: DisplayPort sleep D3 mode: 3.2 mA (typ) 10 A (typ) when in deep power-saving state (when HPD is LOW) Configurable via GPIO control pins Power Supply 1.7 V to 1.9 V Small high performance HWFLGA36 package 2.1 mm x 6.0 mm x 0.6 mm with 0.4 mm pitch ESD HBM 1.5 kV CDM 1 kV Operating temperature range -20 C to +85 C 3 Applications DisplayPort source applications Smartphones and tablets Notebooks, AIO and desktop computers Hub or dock devices DisplayPort sink applications Docking stations Display units 4 Ordering information Table 1.Ordering information Type number Topside Package marking Name Description Version PTN3816EW 16 HWFLGA36 plastic thermal enhanced very very thin fine- SOT1948-1 pitch land grid array package 4.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum order Temperature number quantity PTN3816EW PTN3816EWY HWFLGA36 reel dry pack, SMD, 7000 T = -20 C to 85 C amb 13 Q1 PTN3816 All information provided in this document is subject to legal disclaimers.
