Description
The STDP2690 is a high-speed DisplayPort to DisplayPort dual mode converter IC targeted for
applications such as audio-video accessories, docking stations, Thunderbolt storage devices, etc. This
device includes a VESA DP Standard Ver. 1.2a compliant receiver and transmitter, implementing single
link DisplayPort input and output ports comprising four Main lanes, AUX CH, and HPD.
The STDP2690 uses MegaChips’ latest generation DisplayPort dual mode transmitter technology that
supports both DisplayPort and TMDS signal formats (DP++). DisplayPort receiver and transmitter
support HBR2 speed, a data rate of 5.4 Gbps per lane with a total bandwidth of 21.6 Gbps link rate. The
transmitter is capable of supporting HDMI or single link DVI output through a passive level translator
(dongle). When configured as HDMI output, this device supports link rate up to 2.97 Gbps that
corresponds to a pixel rate of 297 MHz, adequate for handling video timings up to FHD 120 Hz 3D
formats. This device delivers deep color video up to 16-bits per color at 1080p 60 Hz and lower video
resolutions. The STDP2690 allows audio transport from the source to desired audio rendering devices
over the DP++ output or through the SPDIF port. The audio signal from the source can be routed
simultaneously to DP++ and SPDIF output ports. For example, the STDP2690 allows routing of any two
audio channels on the SPDIF port, while transporting up to eight channels on the DP++ port.
The STDP2690 supports RGB and YCbCr colorimetric formats with color depth of 16, 12, 10, and 8 bits.
This device features HDCP 1.3 content protection scheme with an embedded key option for secure
transmission of digital audio-video content. It also operates as an HDCP repeater for the downstream
sink. The eDP authentication option ASSR (Alternative Scrambler Seed Reset) is supported for
embedded application.
The AUX-to-I2C translator in the STDP2690 allows the upstream DisplayPort source to access EDID and
transfer MCCS commands to a downstream sink over the HDMI interface when used with a level
translator. This device has an on-chip microcontroller with SPI and I2C host interface for system
configuration purposes. STDP2690 can be configured with an external SPI Flash for custom
applications. In addition, it allows register level configuration from an external host controller through I2C
interface.

Note:
(1) – LFBGA stands for Low profile Fine pitch Ball Grid Array.
– Low profile: 1.20mm < A = 1.70mm / Fine pitch: e < 1.00mm.
– The total profile height (Dim A) is measured from the seating plane “C” to the top of the
component.
– The maximum total package height is calculated by the RSS method (Root Sum Square):
A Max = A1 Typ + A2 Typ + A4 Typ + v (A1² + A2² + A4² tolerance values).
(2) – The typical ball diameter before mounting is 0.50mm.
(3) – The tolerance of position that controls the location of the pattern of balls with respect to
datums A and B. For each ball there is a cylindrical tolerance zone eee perpendicular to
datum C and located on true position with respect to datums A and B as defined by e. The
axis perpendicular to datum C of each ball must lie within this tolerance zone.
4) – The tolerance of position that controls the location of the balls within the matrix with
respect to each other. For each ball there is a cylindrical tolerance zone fff perpendicular to
datum C and located on true position as defined by e. The axis perpendicular to datum C of
each ball must lie within this tolerance zone. Each tolerance zone fff in the array is
contained entirely in the respective zone eee above The axis of each ball must lie
simultaneously in both tolerance zones.
(5) – The terminal A1 corner must be identified on the top surface by using a corner
chamfer, ink or metalized markings, or other feature of package body or integral heat slug.
– A distinguishing feature is allowable on the bottom surface of the package to identify the
terminal A1 corner. Exact shape of each corner is optional.

The values in the Max column represent absolute maximum current consumption under

environment that includes some discreet components. Other conditions include: a) Power
measurement values are to be used for regulator sizing only, and not directly for package
