Page 6: General Description
2 General description The FMC150 is a four channel ADC/DAC FMC daughter card. The card provides two 14-bit A/D channels and two 16-bit D/A channels which can be clocked by an internal clock source (optionally locked to an external reference) or an externally supplied sample clock. In addition there is one trigger input for customized sampling control. -

4.1 Phycisal specifications 4.1.1 Board Dimensions The FMC150 card complies with the FMC standard known as ANSI/VITA 57.1. The card is a single width conduction cooled mezzanine module (with region 1 and front panel I/O). The front area holds 6 MMCX or 6 SSMC connectors. The stacking height is 10mm. -

Figure 3: Bezel design 4.2 Electrical specifications The FMC150 card is designed to operate in LVDS mode. The FMC150 requires a VADJ voltage of +2.5V. The data converters operate in LVDS mode (clock and data pairs). All other status and control signals, like serial communication busses, operate at LVCMOS 2.5V level. -

The protection can be removed by switching on SW1 of the DIP switch (silk screen label is “WR EN”). 4.2.1 JTAG The FMC150 card TDO pin is connected to the TDI pin to ensure continuity of the JTAG chain. TCK, TMS and TRST are left unconnected on the FMC150. 4.2.2 FMC Connector The low-pin count connector has only bank LA available and two dedicated LVDS clock pairs. -

4.7.2 Architecture The FMC150 card offers a clock architecture that combines flexibility and high performance. Components have been chosen in order to minimize jitter and phase noise to reduce degradation of the data conversion performance. The user may choose to use an external sampling clock or an internal sampling clock. -

5 Controlling the FMC150 Good knowledge of the internal structure and communication protocol of relevant onboard devices is required for controlling the FMC150. This document only provides guidelines for programming the devices. For detailed information it is recommended to refer to the datasheets listed in the related documents section of this document. -
