Renesas Electronics 8V19N882 RF Clock Generator & Jitter Attenuator
Renesas Electronics 8V19N882 RF Sampling Clock Generator and Jitter Attenuator is a high-performance clock solution for conditioning and frequency/phase management of wireless base station radio equipment boards. The 8V19N882 is optimized to deliver excellent phase noise performance as required in 4G, 5G, and including mmWave radio implementations.
The Renesas 8V19N882 RF Sampling Clock Generator and Jitter Attenuator support JESD204B (subclass 0 and 1) and JESD204C. A two-stage PLL architecture provides both jitter attenuation and frequency multiplication. The first stage PLL is the jitter attenuator and uses an external VCXO for the best possible phase noise characteristics. In the second stage, PLL locks on the first PLL output signal and synthesizes the target frequency. The second stage PLL, can use the internal or an external high-frequency VCO.
The 8V19N882 is configured through a 3/4-wire SPI interface, and reports lock and signal loss status in internal registers and via the GPIO[1:0] outputs. Internal status bit changes are reported via a GPIO output.
