Description
The FMC229 is an FPGA Mezzanine Card (FMC) per VITA 57 specification. The boardutilizes TI DAC39J84 with Quad DAC at 16-bit @ 2.8 GSPS.
The module has a dual high performance broadband I/Q modulator with a fractional-N PLLand low noise multicore VCO’s. The baseband inputs mix with the Local Oscillator (LO)generated internally or provided externally, and convert it to a single ended RF. TheFMC229 allows both internal and external LO signals for the mixers. The internal LO isgenerated by an on-chip VCO. The front panel also has Trig In/Out and CLK In ports.
- General output LO range: 256.25 MHz to 4100 MHz (based on internal orexternal VCO)
- External VCO input frequency range: 250 MHz to 4200 MHz (-10 dBm to+10 dBm)
- A cut-off frequency of 650 MHz of the low pass filter on I and Q providing amaximum analog bandwidth of 1300 MHz (limited to 200 MHz with LO frequencyat 4100 MHz)
- Typical RF output between 400 MHz to 4200 MHz.
