TC358770AXBG
Overview
This Functional Specification defines operation of TC358770AXBG /
TC358777XBG chip, which concatenates two DSISM streams of video
packets, one from each DSI link into a single DisplayPortTM video
P-VFBGA100-0505-0.40-001
stream.
Weight: 40 mg (Typ.)
The only difference between TC358770AXBG and TC3587777XBG is
the package size. TC358770AXBG housed in a 5.0 mm by 5.0 mm
size package with 0.4 mm ball pitch. While TC358777XBG housed in
a 7.0 mm by 7.0 mm size package with 0.65 mm ball pitch.
TC358777XBG
TC358770AXBG / TC358777XBG exhibits two independent 4-data
lane DSI receivers and one 4-lane DisplayPortTM transmitter. Each
DSI link data lane can receive data up to 1 Gbps/lane, with up to 8
Gbps total input data rate. Each DSI receiver link can activate 0-, 1-,
2-, 3- or 4-data lanes independently. DP main link can toggle bit rate
at either 1.62 or 2.7 Gbps per lane, with maximum output data rate at
P-VFBGA80-0707-0.65-001
Weight: 66 mg (Typ.)
8.64 Gbps. DP transmitter is able to operate with 1-, 2 or 4-lanes in its main link.
The target application is for high resolution DisplayPortTM panels, whose bandwidth requirement cannot
be met by a single 4-data lane DSI link @4 Gbps. TC358770AXBG is an ideal bridge chip which
enables application processors, or hosts, with dual DSI links to drive up to 2560 x 2048 x 24 (or 18)
DisplayPortTM panels @60fps.
