8V19N490-24规格书详情
Description
The 8V19N490-24 is a fully integrated FemtoClock® NG jitter
attenuator and clock synthesizer designed as a high-performance
clock solution for conditioning and frequency/phase management of
wireless base station radio equipment boards. The device is
optimized to deliver excellent phase noise performance as required
in GSM, WCDMA, LTE, and LTE-A radio board implementations. The
device supports JESD204B subclass 0 and 1 clocks.
A two-stage PLL architecture supports both jitter attenuation and
frequency multiplication. The first stage PLL is the jitter attenuator
and uses an external VCXO for best possible phase noise
characteristics. The second stage PLL locks on the VCXO-PLL
output signal and synthesizes the target frequency.
The device supports the clock generation of high-frequency clocks
from the selected VCO and low-frequency synchronization signals
(SYSREF). SYSREF signals are internally synchronized to the clock
signals. Delay functions exist for achieving alignment and controlled
phase delay between system reference and clock signals and to
align/delay individual output signals. The four redundant inputs are
monitored for activity. Four selectable clock switching modes are
provided to handle clock input failure scenarios. Auto-lock,
individually programmable output frequency dividers, and phase
adjustment capabilities are added for flexibility.
The device is configured through a 3-wire SPI interface and reports
lock and signal loss status in internal registers and via a lock detect
(LOCK) output. Internal status bit changes can also be reported via
the nINT output. The 8V19N490-24 is ideal for driving converter
circuits in wireless infrastructure, radar/imaging, and
instrumentation/medical applications. The device is a member of the
high-performance clock family from IDT.
