TSW1265EVM Evaluation Module
The TSW1265EVM evaluation module is a wideband, dual-receiver reference design and evaluation
platform. The signal chain allows conversion from RF to bits using a dual-channel downconversion mixer,
the LMH6521 dual-channel, digitally controlled variable gain amplifier (DVGA), and the ADS4249 14-bit
250-MSPS analog-to-digital converter (ADC). The TSW1265EVM also includes the LMK04800 dual-PLL
clock jitter cleaner and generator to provide an onboard low-noise clocking solution. A provided software
GUI allows for configuration of the ADS4249 and LMK04800. Either the GUI or an FPGA using the high-
speed connector can control the gain of the LMH6521 DVGA. The EVM mates with the TSW1400 pattern
capture and generation card to capture data from the ADS4249. Then, the High Speed Data Converter
Pro software tool can perform signal analysis. The TSW1265EVM product folder on the TI web site
contains the EVM schematic, bill of materials, and layout files.

3.4.1 Clocking The TSW1265EVM allows for multiple clocking configurations by using the LMK04800 clock jitter cleaner and generation chip. The board comes preinstalled with a 20-MHz crystal which can be used to generate the sampling clock. The default for the board is a 250-MHz sampling clock. - Page 13 2 and 3. This configures the CPLD to route the gain from the connector rather than from the USB connection.
