Product details
Overview
8N0QV01EH-0009CDI from Renesas Electronics (formerly IDT) is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) with I²C reprogrammability, 15.476–260 MHz output range, ±2.5 to ±727.5 ppm absolute pull range, and RMS phase jitter of 0.635 ps (12 kHz–20 MHz) at 156.25 MHz. It serves as a precision timing source in wireless infrastructure baseband units requiring dynamic frequency selection and low-jitter clock synthesis.
For engineers reviewing the 8N0QV01EH-0009CDI datasheet, 8N0QV01EH-0009CDI pinout, 8N0QV01EH-0009CDI application, or 8N0QV01EH-0009CDI equivalent, this page delivers verified technical context, pin-level design meaning, real-world application mappings, and validated alternative options for telecom-grade VCXO selection.
Technical Context
The 8N0QV01EH-0009CDI implements a fourth-generation FemtoClock® NG PLL architecture with a 114.285 MHz fundamental crystal reference, a 1950–2600 MHz VCO, and fractional-N feedback using 7-bit integer (MINT) and 18-bit fractional (MFRAC) dividers. Its four independent configuration registers (P₀–P₃, MINT₀–MINT₃, MFRAC₀–MFRAC₃, N₀–N₃) are selected via FSEL0/FSEL1 and support immediate frequency switching with ≤1 ms settling time.
It integrates an on-chip ADC for VCXO control voltage (VC) gain programming (7.57–477.27 ppm/V), supports dual supply modes (2.5 V or 3.3 V), and features LVCMOS/LVTTL-compatible control inputs with internal 50 kΩ pullup/pulldown resistors - enabling direct FPGA interface without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 15.476 MHz to 260 MHz - supports wideband telecom clocking including 156.25 MHz Ethernet, 122.88 MHz CPRI, and 100 MHz LTE baseband. |
| Frequency Resolution | 435.9 Hz ÷ N - enables sub-Hz tuning granularity when N = 1, critical for precise phase alignment in coherent radio systems. |
| Absolute Pull Range (APR) | ±2.5 to ±727.5 ppm - programmable via I²C to match loop filter bandwidth and stability requirements of specific PLL applications. |
| RMS Phase Jitter (156.25 MHz) | 0.635 ps (12 kHz–20 MHz) - meets stringent OC-192/SONET and IEEE 802.3ba 100GBASE-R jitter budgets. |
| Supply Voltage | 2.5 V or 3.3 V - dual-rail compatibility simplifies integration into mixed-voltage FPGA/ASIC timing subsystems. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade wireless infrastructure deployment in outdoor macrocells and remote radio heads. |
| Package | 10-lead ceramic 5 mm × 7 mm × 1.55 mm (CD package) - RoHS 6-compliant, low-profile surface-mount footprint with thermal resistance θJA = 49.4°C/W (no airflow). |
Pinout & Package
10-lead ceramic CD package (5 mm × 7 mm × 1.55 mm), RoHS 6-compliant, lead-free, with exposed pad not electrically connected. Pin 7 (DNU) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VC | VCXO control voltage input | Analog tuning port; gain programmable via ADC_GAIN[5:0] register; nominal tuning voltage = VDD/2; impedance = 500 kΩ. |
| OE | Output enable input | Asynchronous LVCMOS/LVTTL control; OE = 0 places Q output in high-impedance state - enables clock multiplexing without external switches. |
| GND | Power ground | Primary return path for core logic and output driver; requires low-inductance connection to PCB ground plane. |
| FSEL1, FSEL0 | Default frequency select inputs | 2-bit LVCMOS/LVTTL address selecting one of four factory-programmed P/M/N configurations at power-up; internal 50 kΩ pulldowns. |
| Q | LVCMOS clock output | Single-ended 2.5 V/3.3 V output; 15 Ω (3.3 V) / 19 Ω (2.5 V) drive strength; 45–55% duty cycle; rise/fall time ≤700 ps (3.3 V). |
| VDD | Positive supply | Accepts 2.5 V ±5% or 3.3 V ±5%; requires local 0.1 µF decoupling capacitor placed directly on device side of PCB. |
| SDATA | I²C data input | Open-drain compatible; internal 50 kΩ pullup; supports standard/fast-mode I²C up to 400 kHz for register programming. |
| SCLK | I²C clock input | Input clock for I²C interface; internal 50 kΩ pullup; synchronizes all register writes and reads to external controller. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-frequency default selection | Four factory-configured P/M/N sets mapped to FSEL[1:0], enabling instant boot-time clock selection without I²C initialization. |
| Fractional-N PLL with delta-sigma modulation | Enables ultra-fine frequency resolution (435.9 Hz ÷ N) and optimized noise shaping - reduces spurs and improves phase noise floor vs. integer-N designs. |
| Volatile I²C register architecture | All four configuration registers retain user-programmed values until power cycle, allowing field updates without firmware changes or OTP reprogramming. |
| Programmable VCXO gain (KV) | Gain adjustable from 7.57 to 477.27 ppm/V (3.3 V) via ADC_GAIN register - permits matching to custom loop filter dynamics in closed-loop PLL systems. |
| Low-jitter LVCMOS output | 0.635 ps RMS phase jitter (12 kHz–20 MHz) at 156.25 MHz meets ITU-T G.8262 EEC-2 and Telcordia GR-1244-CORE requirements for synchronous equipment clocks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-PROG from Silicon Labs | Uses DSPLL architecture with integrated crystal; no external VC input; fixed 10-ppm initial accuracy vs. ±10 ppm for 8N0QV01EH-0009CDI. | Lacks analog VC tuning - unsuitable for closed-loop PLLs requiring continuous frequency adjustment; better for open-loop clock generation. | Select Si510-PROG only if VC input is unnecessary and board space constraints favor single-chip integration over discrete XO+PLL. |
| AK2A-156.250MHZ-T from Abracon | Fixed-frequency VCXO (156.25 MHz only); APR = ±50 ppm; no I²C interface; 7-pin SMD package. | Cannot be reprogrammed; limited to single frequency; lacks quad-default selection and fractional-N flexibility. | Choose AK2A-156.250MHZ-T only for cost-sensitive, static-clock applications where frequency agility and APR range are not required. |
Compared with Si510-PROG and AK2A-156.250MHZ-T, the 8N0QV01EH-0009CDI uniquely combines analog VC tuning, quad-power-up frequencies, and I²C programmability - making it the only option among the three suitable for adaptive, closed-loop telecom timing systems requiring dynamic frequency and pull-range reconfiguration.

FAQ
What is the function of the DNU pin on the 8N0QV01EH-0009CDI?
Pin 7 is marked DNU (Do Not Use) and must remain unconnected. It has no internal circuit connection and is reserved for future package variants. Connecting or routing to this pin may cause unpredictable behavior or damage. The 8N0QV01EH-0009CDI datasheet explicitly states "Do not connect" - no pullup, pulldown, or signal routing is permitted.
Does the 8N0QV01EH-0009CDI require an external crystal?
No, the 8N0QV01EH-0009CDI integrates a third-overtone 114.285 MHz crystal within its ceramic package. It is a complete, self-contained VCXO - no external crystal, load capacitors, or oscillator circuitry is needed. This internal resonator is factory-trimmed and sealed, ensuring stable aging performance (±3 ppm over 10 years).
Can the 8N0QV01EH-0009CDI operate at both 2.5 V and 3.3 V simultaneously?
No, the 8N0QV01EH-0009CDI operates exclusively at either 2.5 V or 3.3 V - not both. VDD must be supplied at one nominal voltage within ±5% tolerance (2.375–2.625 V or 3.135–3.465 V). Mixing supplies or applying intermediate voltages violates Absolute Maximum Ratings and may cause latch-up or permanent damage to the 8N0QV01EH-0009CDI.
How does the FSEL0/FSEL1 pin configuration interact with I²C programming on the 8N0QV01EH-0009CDI?
FSEL0/FSEL1 select which of the four volatile I²C configuration registers (0–3) is active at power-up. After boot, I²C can rewrite any register - including the currently selected one - but changing FSEL0/FSEL1 triggers immediate output frequency switching to the newly loaded register values. The 8N0QV01EH-0009CDI datasheet recommends writing to an unselected register first, then toggling FSEL to avoid transient glitches.
Is the 8N0QV01EH-0009CDI pin-compatible with earlier IDT8N0QV01 revisions?
Yes, the 8N0QV01EH-0009CDI maintains identical pinout, package dimensions (10-lead CD), and electrical characteristics with all IDT8N0QV01Hxx variants. Revision H (including 8N0QV01EH-0009CDI) supersedes Rev G and earlier; all functional and timing specifications remain consistent across H-series devices per the March 2014 datasheet revision A.
