SNAU288 December 2023 LMX1906-SP
The LMX1906-SP EVM is an ultra-low additive-jitter RF buffer, divider, and multiplier, with integrated SYSREF generation capability. A separate auxiliary clock divider can be used for FPGAs or other logic ICs. Each RF output (and the logic clock) is paired with a complementary SYSREF output with picosecond-precision delay-tuning capability, and can be operated as a generator (with synchronization capability across multiple devices) or as a repeater.
The EVM can be operated with a 3.3-V supply voltage when the onboard LDOs are utilized. The LDOs can be bypassed, in this case the supply voltage is 2.5-V.
The EVM contains LMX1906-SP, two LDOs, a microcontroller and an IO expander. LMX1906-SP and the LDOs can support –55ºC to +125ºC operation. For high temperature evaluation, use an USB2ANY dongle to control the EVM.
