PRODUCTION DATA.
The output buffers are differential push-pull type buffers, thus no external pullup to VCC is required. The output impedance of the buffer is very small, and as such, the buffer can be AC-coupled to drive a 50-Ω load. Output power of the buffer can be programed to various levels. The buffer can be disabled while still keeping the PLL in lock. Buffer A supports direct VCO output or divided down output. Buffer B supports direct VCO output, divided down output or SYSREF output.
