Product details
Overview
8N3QV01EG-0016CDI from Renesas Electronics is a quad-frequency programmable VCXO using fourth-generation FemtoClock® NG technology, delivering LVPECL differential output with RMS phase jitter of 0.487 ps (12 kHz–20 MHz) at 156.25 MHz, ±20 ppm frequency stability, and absolute pull-range programmability from ±4.5 to ±754.5 ppm - deployed in wireless infrastructure baseband timing and 5G fronthaul synchronization.
For engineers reviewing the 8N3QV01EG-0016CDI datasheet, 8N3QV01EG-0016CDI pinout, 8N3QV01EG-0016CDI application, or 8N3QV01EG-0016CDI equivalent, this page provides verified package mapping (CD10 ceramic 5 mm × 7 mm), I²C-programmable PLL register architecture, factory-default frequency selection via FSEL0/FSEL1, and validated alternative options for telecom-grade VCXO replacement.
Technical Context
The 8N3QV01EG-0016CDI integrates a 114.285 MHz 3rd-overtone crystal oscillator, a fractional-N PLL with 7-bit integer (MINT) and 18-bit fractional (MFRAC) feedback dividers, and a 1950–2600 MHz VCO - enabling precise synthesis across two disjoint bands: 15.476–866.67 MHz and 975–1300 MHz. Its P/M/N divider configuration supports four independent power-up frequencies stored in volatile I²C registers.
Control is implemented via dual LVCMOS-compatible select pins (FSEL0/FSEL1), an open-drain I²C interface (SDATA/SCLK), and an asynchronous OE input. The VC pin accepts analog tuning voltage (0–VCC) with programmable oscillator gain (7.57–477.27 ppm/V), while internal pulldowns/pullups eliminate external biasing for FSEL/OE lines.
Key Specifications

| Startup Time | 20 ms max from power-on to stable output - critical for fast-recovery 5G radio control loops. |
Pinout & Package
8N3QV01EG-0016CDI uses a RoHS-compliant 10-lead ceramic CLCC package (CD10), 5.0 mm × 7.0 mm × 1.55 mm body, 2.54 mm pitch, with metallized bottom pad and NSMD land pattern per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VC) | VCXO control voltage input | Analog tuning port; gain programmable (7.57–477.27 ppm/V); requires clean 0–3.3 V source. |
| 2 (OE) | Output enable (LVCMOS/LVTTL) | Asynchronous active-high control; pulls Q/nQ to high-Z when low - enables dynamic clock gating. |
| 3 (VEE) | Negative supply rail | Ground reference for LVPECL outputs; must be solidly connected to system ground plane. |
| 4 (FSEL0) | Default frequency select (LSB) | Pulldown-biased input; selects one of four factory-configured PLL register sets on power-up. |
| 5 (FSEL1) | Default frequency select (MSB) | Pulldown-biased input; combined with FSEL0, determines initial P/M/N configuration (0–3). |
| 6 (Q) | LVPECL positive output | Differential clock output; 50 Ω termination to VCC − 2 V required for signal integrity above 1 GHz. |
| 7 (nQ) | LVPECL negative output | Complementary to Q; forms true differential pair - essential for common-mode noise rejection. |
| 8 (VCC) | Positive supply (3.3 V) | Core and output driver supply; decoupling (0.1 µF + 10 µF) mandatory near pin for sub-ps jitter. |
| 9 (SDATA) | I²C bidirectional data (open-drain) | Configures PLL registers, APR, polarity; requires external pullup (typically 1–10 kΩ to VCC). |
| 10 (SCLK) | I²C clock input | LVCMOS-compatible clock; max 400 kHz standard-mode; synchronizes register writes to avoid glitches. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5332A-D-GM | Multi-output clock generator (12 outputs), integrated jitter cleaner; no VCXO tuning voltage input; fixed 3.3 V supply. | Replaces discrete VCXO+PLL combos in complex timing trees; not suitable for analog loop control or APR tuning. | Select when system requires multiple synchronized clocks and jitter cleaning, not analog VCXO behavior. |
| 8A34001C-001LG | Quad-output femtosecond jitter clock generator; supports JESD204B subclass 1; no VCXO mode or APR programming. | Targeted at high-speed serial link timing (PCIe Gen5, CXL); lacks analog tuning interface for PLL loop integration. | Select for deterministic low-latency clock distribution where VCXO control voltage is unnecessary. |
Compared with Si5332A-D-GM and 8A34001C-001LG, the 8N3QV01EG-0016CDI uniquely combines analog VCXO tunability, quad-frequency default selection, and sub-0.5 ps jitter in a single-output 10-pin ceramic package - making it irreplaceable in closed-loop RF synchronization where APR and VC pin control are mandatory.

FAQ
What is the supply voltage requirement for the 8N3QV01EG-0016CDI?
The 8N3QV01EG-0016CDI operates exclusively at 3.3 V ±5%, as confirmed by its order code 'E' and DC electrical characteristics in Table 5A of the datasheet. It does not support 2.5 V operation - attempting 2.5 V supply will result in undefined behavior or failure to start.
How many default frequencies does the 8N3QV01EG-0016CDI support at power-up?
The 8N3QV01EG-0016CDI supports exactly four factory-programmed default frequencies selected by the FSEL0 and FSEL1 pins at power-up. These correspond to pre-loaded P/M/N register configurations (P0–P3, MINT0–MINT3, etc.) and are reprogrammable via I²C after initialization.
What is the guaranteed phase jitter performance of the 8N3QV01EG-0016CDI at 156.25 MHz?
The 8N3QV01EG-0016CDI guarantees 0.487 ps RMS phase jitter (typical) measured over 12 kHz–20 MHz offset at 156.25 MHz output, per Table 6B of the datasheet. This value is validated under industrial temperature conditions and 3.3 V supply.
Can the 8N3QV01EG-0016CDI be used with 2.5 V LVPECL termination?
No - the 8N3QV01EG-0016CDI is specified only for 3.3 V LVPECL operation (order code 'E'). Its output stage is characterized for VOH = VCC − 0.8 V and VOL = VCC − 1.5 V at 3.3 V; 2.5 V termination violates AC specifications and risks signal integrity degradation.
What package type and dimensions does the 8N3QV01EG-0016CDI use?
The 8N3QV01EG-0016CDI uses the CD10 package: a lead-free 10-lead ceramic CLCC measuring 5.0 mm × 7.0 mm × 1.55 mm, with 2.54 mm pitch and metallized bottom pad. Package outline drawing PSC-4246-01 confirms mechanical tolerances and IPC-7351B land pattern compliance.
