NASA1 is a 4 channel implementation with interfaces for three types of telemetry plus UART and Parallel Ports.
Channel 0 provides the "LADEE - LLST" interface supported with DMA and 8Kx32 of FIFO in each direction. PLLA is used to set the TX reference frequency typically 40 Mhz. The interface is LVDS.
Channel 1 provides the "NMS" interface supported with DMA and 8Kx32 of FIFO in each direction. PLLB is used to set the TX reference frequency typically 1-10 MHz. The interface is RS-422 / RS-485.
Channel 2 provides the "UART" interface supported with DMA and 1Kx32 of FIFO in each direction. PLLC is used to set the reference frequency typically 14.7456 MHz. further divided to provide all of the standard baud rates. The interface is RS-422 / RS-485.
Channel 3 provides the "Uplink and Downlink" interface supported with DMA and 1Kx32 of FIFO in each direction. Manchester encoded. PLLD is used to set the reference frequency typically 8 MHz. further divided within the channel to provide the 8x and 2x clocks used for the Downlink and Uplink respectively. The rates are divided separately allowing for asymmetrical operation. The interface is RS-422 / RS-485.
The remaining IO are used for a 14 bit parallel port with bit level direction control. RS-422/ RS-485 IO.
