Product details

Overview

5P49V6968A000NDGI from Renesas Electronics is a VersaClock® 6E programmable clock generator supporting PCIe 1.0–5.0, Ethernet switch/router timing, and FPGA/processor clocking. It delivers <0.5ps RMS phase jitter on outputs, accepts dual redundant LVCMOS reference inputs (1–200 MHz), and generates up to 11 configurable clock outputs with independent spread-spectrum control.

For engineers reviewing the 5P49V6968A000NDGI datasheet, 5P49V6968A000NDGI pinout, 5P49V6968A000NDGI application, or 5P49V6968A000NDGI equivalent, key selection criteria include its 48-VFQFPN package, I²C-programmable OTP configuration, differential (LVPECL/LVDS/HCSL) and LP-HCSL output flexibility, and industrial temperature range (−40°C to +85°C).

Technical Context

The 5P49V6968A000NDGI integrates a high-performance fractional-N PLL with 2.5–2.9 GHz VCO range and four banks of in-system programmable OTP memory. Its architecture supports glitchless manual switchover between two redundant clock inputs and enables per-output spread-spectrum modulation (±0.1% to ±2.5%) for EMI reduction.

Three universal outputs (OUT1/2/4) support differential (LVPECL/LVDS/HCSL, 1 kHz–350 MHz) or single-ended (LVCMOS, 1 kHz–200 MHz) operation with mixed 1.8V/2.5V/3.3V I/O VDDs; eight additional LP-HCSL outputs (OUT3/5–11) operate at 1.8V across 1 kHz–200 MHz.

Pin/Terminal	Circuit Role	Design Meaning
OUT1, OUT1B	Differential clock output pair	Configurable as LVPECL/LVDS/HCSL (1 kHz–350 MHz) or single-ended LVCMOS (1 kHz–200 MHz); VDDO1 supplies 1.8–3.3V
OUT2, OUT2B	Differential clock output pair	Same configuration flexibility as OUT1; VDDO2 independently sets output voltage level
OUT4, OUT4B	Differential clock output pair	Supports same I/O standards; VDDO4 enables independent 1.8–3.3V biasing
OUT3, OUT5–OUT11, OUT3B, OUT5B–OUT11B	LP-HCSL clock outputs	1.8V-only, 1 kHz–200 MHz; optimized for low-power PCIe and storage interfaces
XIN/REF, XOUT	Clock input / crystal oscillator interface	Accepts single-ended LVCMOS reference (≤1.2 V) or drives external crystal (8–40 MHz); internal oscillator eliminates need for external XO
SEL0/SCL, SEL1/SDA, OUT0_SEL_I2CB	I²C interface / hardware select control	Configurable I²C address (0xD0 or 0xD4); OUT0_SEL_I2CB latches boot mode to assign pins 13/14 as SCL/SDA or SEL0/SEL1
SD/OE	Shutdown / output enable	Active-low dual-function pin: SD mode powers down chip; OE mode tri-states or drives outputs low/high per programming
OEA, OEB, OE_buffer	Group output enables	OEA controls OUT3/5/6/11; OEB controls OUT7–10; OE_buffer enables all LP-HCSL outputs (3/5–11) - enables dynamic power gating

Key Features

Feature	Design Value
Four OTP memory banks	Enables field-updatable configurations for multiple operating modes without reprogramming hardware
Glitchless manual switchover	Allows real-time selection between two redundant reference clocks without output interruption - critical for telecom failover systems
Mixed-voltage I/O domains	Independent VDDOx rails (1.8V/2.5V/3.3V) per output bank permit coexistence of legacy and high-speed interfaces on one device
Programmable output skew	Adjusts relative phase alignment between outputs to compensate for PCB trace length mismatches in high-speed parallel buses

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable clock generator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si5341-B-GM	Higher channel count (12 outputs), integrated jitter attenuator, supports JESD204B deterministic latency; requires external loop filter	Better suited for ultra-low-jitter ADC/DAC clocking in radar/test equipment where sub-100 fs jitter is mandatory	Select Si5341-B-GM when jitter attenuation and deterministic delay are required beyond what the 5P49V6968A000NDGI's PLL can provide
ICS8430I-01T	Fixed 4-output LVDS/LVPECL generator; no I²C programming, no spread spectrum, no OTP memory; simpler register map	Targeted at cost-sensitive, static-clocking applications like basic networking PHYs where configuration flexibility is unnecessary	Choose ICS8430I-01T only if design requires zero configuration overhead and operates within its fixed 100–700 MHz output range

Compared with Si5341-B-GM and ICS8430I-01T, the 5P49V6968A000NDGI balances programmability, jitter performance, and integration - offering OTP-based field reconfiguration, per-output spread spectrum, and mixed-voltage I/O without external components, making it optimal for PCIe, Ethernet, and FPGA platforms requiring both flexibility and industrial reliability.

FAQ

What is the maximum output frequency supported by the 5P49V6968A000NDGI on differential outputs?

The 5P49V6968A000NDGI supports up to 350 MHz on its three universal differential outputs (OUT1/2/4) when configured as LVPECL, LVDS, or HCSL. This specification is validated under recommended operating conditions (VDDO = 1.8–3.3 V, TA = −40°C to +85°C) and meets PCIe Gen4/Gen5 reference clock requirements. The 5P49V6968A000NDGI achieves this using its 2.5–2.9 GHz VCO and fractional-N synthesis architecture.

Does the 5P49V6968A000NDGI support I²C programming, and what are the available addresses?

Yes, the 5P49V6968A000NDGI supports I²C programming via pins SEL0/SCL and SEL1/SDA, which are configurable as I²C bus lines using the OUT0_SEL_I2CB pin at power-up. It offers two selectable I²C slave addresses: 0xD0 and 0xD4 - allowing up to two 5P49V6968A000NDGI devices to share the same I²C bus without address conflict. Configuration is stored in on-chip OTP memory.

How many independent power domains does the 5P49V6968A000NDGI support for its outputs?

The 5P49V6968A000NDGI supports five independent output power domains: VDDO0 (for crystal oscillator and OUT0_SEL_I2CB), VDDO1 (OUT1), VDDO2 (OUT2), VDDO4 (OUT4), and VDDO (shared by OUT3/5–11). Each domain accepts 1.8V, 2.5V, or 3.3V (except VDDO, fixed at 1.8V), enabling mixed-voltage clock distribution - for example, 3.3V LVCMOS for legacy peripherals and 1.8V LP-HCSL for PCIe Gen4 endpoints - all from a single 5P49V6968A000NDGI.

Can the 5P49V6968A000NDGI generate spread-spectrum clocks, and is it configurable per output?

Yes, the 5P49V6968A000NDGI supports independent spread-spectrum modulation on each of its three universal outputs (OUT1/2/4), with programmable spread values from ±0.1% to ±2.5% and modulation frequencies from 30 kHz to 63 kHz. This feature is not available on the eight LP-HCSL outputs (OUT3/5–11). Spread spectrum reduces electromagnetic interference (EMI) peaks without degrading timing margins - a key requirement for FCC/CE compliance in dense compute and networking systems using the 5P49V6968A000NDGI.

What is the startup time and PLL lock time for the 5P49V6968A000NDGI after power-up?

The 5P49V6968A000NDGI has a maximum startup time of 30 ms measured after all VDD supplies reach 90% of target voltage. PLL lock time from shutdown mode is 3–4 ms. These timings include loading configuration bits from OTP memory into PLL registers but exclude EPROM programming time. Startup behavior assumes temperature calibration is enabled; Renesas provides guidance for shorter lock times if required in time-critical applications involving the 5P49V6968A000NDGI.
