The SWH-T-122 is generation 2 in/2 out port
HDMI/DVI splitter & switch which can repeat one HDMI/DVI signal to 2
HDMI/DVI signal sets, support up to 2 different HDMI/DVI
receiving/display terminals. Based on Cleared Edge™technology, it
supports up to 3.4Gbps data rate per channel, compliant with the
HDMI 1.3 / 1.4 specifications. The device incorporates a pair of ODTs, an adaptive equalizer and a CDR circuit on each data channel
of receiver side, and a de-emphasis driver with optional back
terminations on each data channel of transmitter side. The clock
channel feeds a high-performance PLL that regenerates a low jitter
output clock for data recovery. The SWH-T122 process HDCP
decryption / encryption and transmits the data to 2 HDMI/DVI
ports. The HDCP repeater engine in SWH-T122 handles
all the processing required by authentication, decryption and
encryption in hardware. This greatly reduces the external MCU
overhead and firmware complexity. However, for more flexibility,
the SWH-T122 also provides an option of software-controlled
mode in which HDCP operations are entirely controlled by external
MCU. Pre-programmed HDCP key sets ease the use of HDCP function.
However, users can also use external key sets through the ESCL /
ESDA port. The SWH-T122 integrates EDID shadow RAM for
better compatibility and reduced system complexity. Embedded EDID
is accessible to the upstream port before the real EDID is loaded
by the external MCU. Fabricated in an advanced CMOS process, the
HDM220 is provided specified over the 0°C to +70°C
temperature range.
