For engineers reviewing the XFP23VA00.000000I datasheet, XFP23VA00.000000I pinout, XFP23VA00.000000I application, or XFP23VA00.000000I equivalent, key selection criteria include industrial-temperature stability, sub-150 fs jitter performance, LVDS drive capability at 0.000000 MHz, I²C programmability support, and 2.5 × 2.0 mm footprint compatibility with dense PCB layouts.

Technical Context

The XFP23VA00.000000I implements a quartz crystal–referenced PLL architecture with integrated VCO and fractional-N synthesis, enabling precise frequency generation from 15 MHz to 2100 MHz. It supports factory OTP programming for fixed-frequency deployment or field reconfiguration via I²C interface using SDA/SCL pins.

This device operates across three supply voltages (1.8 V/2.5 V/3.3 V), delivers differential LVDS output with 0.44 V typical differential swing and 1.26 V common-mode voltage at 3.3 V, and features OE-controlled output enable/disable with ≤1 ms response time and 5 ms start-up after VDD stabilization.

FAQ

What output type and frequency does the XFP23VA00.000000I provide?

The XFP23VA00.000000I is factory-programmed to deliver a fixed 0.000000 MHz LVDS output. Its designation "XFP" indicates programmable PLL oscillator, "2" specifies 2.5 V supply, "3" denotes LVDS output type, "V" signifies ±25 ppm stability, "A" maps to industrial temperature range (–40°C to +85°C), and "00.000000" encodes the exact programmed frequency. No user tuning is needed in final use.

Does the XFP23VA00.000000I support I²C programming in the field?

Yes, the XFP23VA00.000000I retains full I²C programmability via dedicated SDA (pin 4) and SCL (pin 6) pins, even though it ships with a fixed 0.000000 MHz configuration. This enables field reprogramming for frequency updates, output format changes, or feature activation - provided external host controller and firmware support the Renesas XF register map.

What is the phase jitter specification of the XFP23VA00.000000I and how is it measured?

The XFP23VA00.000000I achieves 120 fs typical phase jitter integrated over the 12 kHz to 20 MHz offset band, measured per IEEE 1139 and JEDEC JESD65B standards. This value is confirmed at multiple frequencies including 250 MHz, 312.5 MHz, and 644.53 MHz - ensuring repeatability across common networking clock rates used in the XFP23VA00.000000I's target applications.

Which package and pin count does the XFP23VA00.000000I use?

The XFP23VA00.000000I uses the 2.5 × 2.0 mm 8-pin LGA package (NJG12) with exposed thermal pad (EPAD). It has 12 functional terminals (including EPAD), with pins 1–2 as NC, pin 3 reserved for VCXO variants, pins 4/6 for I²C, pin 5 for OE, pins 7/11 for VDD domains, pins 8–9 for LVDS differential output, and pins 10/12 for dedicated ground returns - all documented in Renesas R31DS0029EU.

How does the XFP23VA00.000000I handle power supply separation and decoupling?

The XFP23VA00.000000I separates core (VDD Core, pin 11) and output (VDD Output, pin 7) supplies to minimize noise coupling. Each requires a dedicated 0.01 µF ceramic capacitor placed within 2 mm of its respective pin and connected to low-inductance ground. The EPAD must be soldered to a solid ground plane to ensure thermal stability and reduce ground bounce during high-speed LVDS edge transitions.
