Product details
Overview
5PB1104CMGK from Renesas Electronics is a high-performance 1:4 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, features synchronous glitch-free output enable (OE), and operates across –40°C to +125°C (AEC-Q100 Grade 1).
For engineers reviewing the 5PB1104CMGK datasheet, 5PB1104CMGK pinout, 5PB1104CMGK application, or 5PB1104CMGK equivalent, this page provides verified specifications, validated pin assignments for its 8-pin DFN package, confirmed automotive-grade thermal and jitter performance, and real-world timing integrity requirements for ADAS sensor synchronization.
Technical Context
The 5PB1104CMGK implements a synchronous output enable architecture that eliminates intermediate incorrect clock cycles during OE transitions-critical for deterministic timing in safety-critical radar subsystems. Its internal termination matches 50Ω transmission lines, reducing external component count while maintaining signal integrity up to 200 MHz.
It uses rail-to-rail LVCMOS input logic with 3.3V-tolerant CLKIN, supports VDD/2 switching thresholds, and achieves sub-50 ps pin-to-pin skew across all four outputs under matched loading conditions-enabling precise multi-channel sampling alignment in time-of-flight sensing applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5PB1104CMGI | Industrial temperature range (–40°C to +85°C); same pinout, electrical specs, and DFN-8 package | Not AEC-Q100 qualified; unsuitable for under-hood automotive use | Select when operating environment remains within industrial grade and cost optimization is prioritized |
| Si53301-D-GM | 2-output, 1.8V–3.3V, 200 MHz max; integrated PLL; higher jitter (90 fs RMS); QFN-24 package | Provides frequency translation capability but lacks synchronous OE and 4-output fanout | Choose only if frequency synthesis is required alongside buffering-and layout space permits larger footprint |
Compared with 5PB1104CMGI and Si53301-D-GM, the 5PB1104CMGK uniquely combines AEC-Q100 Grade 1 qualification, 4-output fanout, synchronous glitch-free OE, and sub-50 fs jitter in a compact 2.0 × 2.0 mm DFN-making it the only drop-in solution for high-reliability, multi-channel automotive radar timing.

FAQ
What is the maximum operating frequency supported by the 5PB1104CMGK?
The 5PB1104CMGK supports an input clock frequency up to 200 MHz across all supply voltages (1.8V, 2.5V, and 3.3V) and temperature ranges, including its full AEC-Q100 Grade 1 specification (–40°C to +125°C). This enables use with high-speed radar chirp generators and gigabit serializer clocks without derating.
Does the 5PB1104CMGK require external termination resistors on its outputs?
No. The 5PB1104CMGK integrates 50 Ω series termination on each LVCMOS output (Y0–Y3), eliminating the need for discrete 50 Ω resistors in standard 50 Ω PCB trace environments. This reduces BOM count, saves board space, and improves signal integrity at 200 MHz by minimizing stub reflections.
How does the synchronous output enable (1G) function prevent clock glitches in the 5PB1104CMGK?
The 5PB1104CMGK's 1G input uses synchronous edge-triggered logic aligned to the CLKIN edge, ensuring outputs transition only on valid clock boundaries. This avoids metastability and eliminates intermediate incorrect clock cycles during enable/disable-critical for preventing data corruption in radar ADC sampling and FPGA configuration sequences.
Is the 5PB1104CMGK pin-compatible with other members of the 5PB11xx family?
No-pin compatibility is limited to same-fanout variants in the same package. The 5PB1104CMGK (1:4, DFN-8) shares pinout with 5PB1102CMG (1:2, DFN-8), but not with 5PB1106CMG (1:6, VFQFPN-16) or 5PB1110NDG (1:10, VFQFPN-20). Always verify package-specific pin assignments before substitution.
What is the additive phase jitter performance of the 5PB1104CMGK at 156.25 MHz?
At 156.25 MHz with a 12 kHz–20 MHz integration bandwidth, the 5PB1104CMGK delivers ≤50 fs RMS additive phase jitter-measured as the difference between output and input jitter. This value is guaranteed across its full AEC-Q100 Grade 1 temperature range and supports high-SNR FFT processing in millimeter-wave radar receivers.
