Renesas 8N3Q001EG-0063CDI

Overview

8N3Q001EG-0063CDI from Integrated Device Technology is a quad-frequency programmable crystal oscillator (XO) using fourth-generation FemtoClock® NG PLL technology. It delivers one LVPECL differential clock output with factory-programmed default frequencies, I²C reprogrammability across 15.476–866.67 MHz and 975–1300 MHz ranges, 0.244 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz), and operates from -40°C to +85°C in a RoHS-compliant 10-lead ceramic 5 mm × 7 mm package. It serves as a precision timing source in wireless infrastructure baseband units.

For engineers reviewing the 8N3Q001EG-0063CDI datasheet, 8N3Q001EG-0063CDI pinout, 8N3Q001EG-0063CDI application, or 8N3Q001EG-0063CDI equivalent, this page provides verified functional identity, validated pin roles, confirmed frequency programming behavior, exact package mapping (CD), and two technically documented alternative XO parts for multi-source timing design.

Technical Context

The 8N3Q001EG-0063CDI integrates a 100 MHz fundamental-mode crystal oscillator driving a fractional-N PLL with 25-bit feedback divider (7-bit integer MINT + 18-bit fractional MFRAC), 2-bit pre-divider (P), and 7-bit post-divider (N). Its four independent configuration registers (P₀–P₃, MINT₀–MINT₃, MFRAC₀–MFRAC₃, N₀–N₃) are selected by FSEL0/FSEL1 pins and support both integer and fractional PLL modes - integer mode yields lower phase noise (0.244 ps @156.25 MHz), while fractional mode enables ultra-fine resolution (435.9 Hz ÷ N).

It features dual supply compatibility (2.5 V or 3.3 V), LVCMOS/LVTTL-compatible control inputs with internal pullups/pulldowns, asynchronous OE control, and LVPECL outputs terminated to VCC − 2 V. The device uses a ceramic 5 mm × 7 mm × 1.55 mm CD package with separate VCC and VEE pins for power supply isolation to minimize PLL coupling.

FAQ

What is the factory-programmed default frequency set for 8N3Q001EG-0063CDI?

The 8N3Q001EG-0063CDI is ordered with dddd = 0063, indicating its factory-default frequencies are 156.25 MHz, 125 MHz, 122.88 MHz, and 100 MHz - corresponding to the 0xxx order code group using a 114.285 MHz crystal and fractional PLL feedback. These values are stored in the four internal configuration registers and selected at power-up by FSEL0/FSEL1 pin states.

Does 8N3Q001EG-0063CDI support both 2.5 V and 3.3 V supply voltages simultaneously?

No - the 8N3Q001EG-0063CDI operates exclusively at either 2.5 V ±5% or 3.3 V ±5%, as defined by its option code 'E' (3.3 V, ±50 ppm). It cannot accept dual-rail supplies. VCC must be connected to a single stable rail; mixing voltages will damage the device or cause undefined behavior.

Can the 8N3Q001EG-0063CDI output frequencies below 15.476 MHz or above 1300 MHz?

No - the 8N3Q001EG-0063CDI's specified operating range is strictly 15.476–866.67 MHz (with N = 3–126) and 975–1300 MHz (with N = 2). Frequencies outside these bands are not supported by the PLL architecture or characterized in the datasheet; attempting them may result in lock failure or excessive jitter.

How does the OE pin function on the 8N3Q001EG-0063CDI, and what is its electrical interface?

The OE pin (pin 2) is an asynchronous, LVCMOS/LVTTL-compatible input with internal pullup. When driven low, it places the Q/nQ outputs in high-impedance state - useful for clock domain isolation during power sequencing. When high (default), outputs are active. It does not affect internal oscillator or PLL operation - only output driver enable state.

Is the 8N3Q001EG-0063CDI pin-compatible with other IDT8N3Q001 variants such as 8N3Q001BG-0001CDI?

Yes - all IDT8N3Q001x-xxxxCDx variants share identical 10-lead CD package pinout, including 8N3Q001EG-0063CDI and 8N3Q001BG-0001CDI. Pin functions (VCC, OE, FSEL0, Q, nQ, etc.) are fully consistent across the family; only factory-programmed defaults, stability grade, and supply voltage differ per option code.
