Description

The 8V19N492-39 is a fully integrated FemtoClock NG jitter

attenuator and clock synthesizer. The device is 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 8V19N492-39 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 8V19N492-39 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 two 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 3/4-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 8V19N492-39 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 Renesas.
