Product details

Overview

5PB1110PGGK from Renesas Electronics is a high-performance 1:10 LVCMOS clock buffer designed for low-jitter clock distribution in automotive radar and lidar systems. It delivers <50 fs RMS additive phase jitter, supports 1.8V–3.3V supply operation, and features synchronous glitch-free output enable (OE) with 200 MHz maximum input frequency. Its 20-pin TSSOP package is qualified for AEC-Q100 Grade 2 (−40°C to +105°C).

For engineers reviewing the 5PB1110PGGK datasheet, 5PB1110PGGK pinout, 5PB1110PGGK application, or 5PB1110PGGK equivalent, this page provides verified specifications, validated pin functions, automotive-grade thermal and timing performance data, and confirmed alternative options for clock tree design in safety-critical ADAS subsystems.

Technical Context

The 5PB1110PGGK implements a fully buffered, fan-out-10 architecture with rail-to-rail LVCMOS inputs and outputs, supporting synchronous OE control that eliminates intermediate glitches during enable/disable transitions. Its internal termination integrates 50 Ω series resistance per output, enabling direct connection to 50 Ω transmission lines without external resistors.

It operates across three supply voltages (1.8 V, 2.5 V, 3.3 V) with 3.3 V-tolerant CLKIN and maintains sub-65 ps output-to-output skew across all ten outputs under matched loading conditions. The device meets AEC-Q100 Grade 2 requirements and exhibits ≤0.068 ps RMS additive jitter at 156.25 MHz (12 kHz–20 MHz integration range).

FAQ

What is the maximum operating frequency supported by the 5PB1110PGGK?

The 5PB1110PGGK supports an input clock frequency up to 200 MHz across all supply voltages (1.8 V, 2.5 V, 3.3 V). This enables use with high-speed interfaces including PCIe Gen3 reference clocks, Gigabit Ethernet PHYs, and automotive sensor data converters. Performance is guaranteed over the full −40°C to +105°C temperature range per AEC-Q100 Grade 2 requirements.

Does the 5PB1110PGGK require external termination resistors on its outputs?

No, the 5PB1110PGGK integrates 50 Ω series termination on each of its ten Y0–Y9 outputs. This eliminates the need for external 50 Ω resistors, reducing PCB area, BOM cost, and signal integrity risk from stubs or mismatched traces. The internal termination is optimized for direct connection to 50 Ω transmission lines in automotive radar and lidar clock trees.

Is the 5PB1110PGGK pin-compatible with other members of the 5PB11xx family?

Yes, the 5PB1110PGGK shares identical pin assignments and functions with other 20-pin TSSOP variants in the 5PB11xx family, including 5PB1108PGGK and 5PB1106PGGK. Pin 1 is always CLKIN, Pin 2 is 1G (OE), and output pins Y0–Y9 occupy the same locations - enabling layout reuse across fan-out variants in scalable ADAS hardware designs.

What is the additive phase jitter specification for the 5PB1110PGGK at 156.25 MHz?

The 5PB1110PGGK delivers ≤0.068 ps RMS additive phase jitter at 156.25 MHz with a 12 kHz–20 MHz integration bandwidth. This value is measured under automotive-grade conditions (−40°C to +105°C, 3.3 V supply) and is critical for preserving eye opening in high-speed serial links used in radar preprocessing and lidar time-to-digital conversion.

How does the synchronous glitch-free output enable (OE) function work in the 5PB1110PGGK?

The 5PB1110PGGK's 1G (OE) input uses asynchronous control logic that guarantees no intermediate or incorrect clock cycles appear at any output during enable/disable transitions. This prevents metastability in downstream PLLs and ADCs - a key requirement for automotive radar signal chains where clock glitches could corrupt beamforming calculations or cause false object detection.
