HDCP Gigabit Multimedia Serial Link Serializer with LVDS System Interface

LVDS Interface Serializer with Integrated Control Channel Is Ideal for Digital Video Applications


Please check latest availability status for a specific part variant.

Description

The MAX9265 gigabit multimedia serial link (GMSL) serializer features an LVDS system interface and high-bandwidth digital content protection (HDCP) encryption for content protection of DVD and Blu-ray™ video and audio data. The serializer pairs with any HDCP GMSL deserializer to form a digital serial link for the transmission of control data and HDCP-encrypted video and audio data. GMSL is an HDCP technology approved by Digital Content Protection (DCP), LLC.

The 3-channel mode serializes three lanes of LVDS data (21 bits), UART control signals, and three audio inputs. The 4-channel mode serializes four lanes of LVDS data (28 bits), UART control signals, three audio inputs, and auxiliary control inputs. The three audio inputs are for I²S audio, supporting a sampling frequency from 8kHz to 192kHz and a sample depth of 4 to 32 bits. The embedded control channel forms a full-duplex differential 9.6kbps to 1Mbps UART link between the serializer and deserializer. An electronic control unit (ECU), or microcontroller (µC), can be located on the serializer side of the link (typical for video display), on the deserializer side of the link (typical for image sensing), or on both sides. The control channel enables ECU/µC control of peripherals on the remote side, such as backlight control, touch screen, and perform HDCP-related operations.

The serial link signaling is AC-coupled CML with 8b/10b coding. For driving longer cables, the serializer has programmable driver pre/deemphasis, and for reduced EMI, has programmable spread spectrum on the serial output. The serial output meets ISO 10605 and IEC 61000-4-2 ESD standards.

The serializer operates with a 1.8V core supply, a 1.8V to 3.3V I/O supply, and a 3.3V LVDS supply. This device is available in a 48-pin TQFP package with an exposed pad and is specified over the
-40°C to +105°C automotive temperature range.
