Схемы параллельно-последовательного и последовательно-параллельного преобразования (Serdes) MAX9205EAI+

SerDes , Параллельно-последовательный Преобразователь, 400 Мбит/с, LVTTL, LVDS, SSOP

The MAX9205EAI+ is a 10bit bus LVDS serializer in 28 pin SSOP package. The serializer transform 10bitwide parallel LVCMOS/LVTTL data into a serial high speed bus low voltage differential signalling data stream. The serializers typically pair with deserializers like the MAX9206 which receive the serial output and transform it back to 10-bit-wide parallel data. The MAX9205 transmit serial data at speeds up to 400Mbps and 660Mbps over PCB traces or twisted-pair cables. Since the clock is recovered from the serial data stream, clock to data and data to data skew that would be present with a parallel bus are eliminated. The serializers require no external components and few control signals. The input data strobe edge is selected by TCLK_R/F. Power down is used to save power when the device is not in use. Upon power-up, a synchronization mode is activated, which is controlled by two SYNC inputs, SYNC1 and SYNC2. The MAX9205 can lock to a 16MHz to 40MHz system clock.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from -40°C to 85°C
• Standalone serializer (vs. SERDES) ideal for unidirectional links
• Framing bits for deserializer resync allow hot insertion without system interruption
• LVDS serial output rated for point to point and bus applications
• Low 34mA supply current
• Programmable active edge on input latch
• Pin compatible upgrades to DS92LV1021 and DS92LV1023
