Схемы параллельно-последовательного и последовательно-параллельного преобразования (Serdes) MAX9247ECM+

SerDes , Параллельно-последовательный Преобразователь, 840 Мбит/с, LVTTL, LVDS, LQFP

The MAX9247ECM+ is a 27bit, 2.5MHz to 42MHz DC balanced LVDS serializer in 48 pin LQFP package. The digital video parallel to serial converter serializes 27bits of parallel data into a serial-data stream. 18bits of video data and 9bits of control data are encoded and multiplexed onto the serial interface, reducing the serial-data rate. The data-enable input determines when the video or control data is serialized. The MAX9247 pairs with the MAX9248/MAX9250 deserializers to form a complete digital video serial link. Interconnect can be controlled-impedance PCB traces or twisted-pair cable. Data encoding reduces EMI and provides DC balance. DC balance allows AC coupling, providing isolation between the transmitting and receiving ends of the interface. The LVDS output is internally terminated with 100 ohm. ESD tolerance is specified for ISO 10605 with ±10KV contact discharge and ±30KV air-gap discharge.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from -40°C to 125°C
• Pre-emphasis improves eye diagram and signal integrity at the output
• Control data sent during video blanking
• Five control data inputs are single-bit-error tolerant
• Programmable phase-shifted LVDS signalling reduces EMI
• Output common-mode filter reduces EMI
• Greater than 10m STP cable drive
• Wide ±2% reference clock tolerance
• Separate input supply allows interface to 1.8V to 3.3V logic
