The Texas Instruments TSW308x evaluation module (EVM) provides a basic platform to evaluate the
DAC348x in a complete RF transmit signal chain. Along with the DAC348x, the EVM includes a
LMK04806B clock jitter cleaner and generator source, which provides the clocks required for the DAC and
the external pattern generator. The EVM also includes on-board TRF3705 I/Q modulators, which provide
IF-to-RF upconversion for basic transmitter evaluation. This EVM is ideally suited for mating with the
Texas Instruments TSW1400 pattern generation board for evaluating WCDMA, LTE, or other high-
performance modulation schemes.

  • Page 3: Introduction

    The TSW308x evaluation module (EVM) is a family of circuit boards that allow designers to evaluate the performance of the Texas Instruments DAC348x digital-to-analog converters (DAC). The DAC348x family consists of DAC3482, DAC3484, and DAC34H84. The 16-bit, 1.25 GSPS, DAC348x has integrated 2x/4x/8x/16x interpolation filters, 32-bit NCO, on-chip PLL, and exceptional linearity at high IFs.
