What Is a Quad HFM Four Channel Interface?
Quad HFM is not a conventional "four pin connector."
Instead, one housing integrates:
four independent coaxial interfaces.
Each channel includes its own:
- center contact;
- dielectric;
- outer shield contact;
- independent signal path.
A quad HFM connector therefore provides:
4 × independent 50Ω coaxial channels.
This is the basis for PCM-ZC-0065 carrying four independent high frequency data links through one compact connector interface.
Why Are Four Independent Coaxial Cables Required ?
Each HFM channel in PCM-ZC-0065 is an independent high speed coaxial transmission path requiring its own center conductor, return/shield path and controlled-impedance geometry.
Therefore, the assembly uses 4 × LEONI DACAR 302-4 50Ω coaxial cables rather than a conventional four-core cable.
This independent-channel architecture maintains 50Ω characteristic impedance, reduces channel to channel coupling and electromagnetic interference, and supports stable signal integrity for SerDes applications such as GMSL and FPD-Link.
Pain Points
Connector frequency alone does not define finished harness performance. PCM-ZC-0065 should be evaluated to its DC 6GHz specification with cable length, VSWR and insertion loss considered.
Core Product Value
PCM-ZC-0065
PCM-ZC-0065 combines dual Quad HFM Z coded high density interfaces with 4 × DACAR 302-4 independent 50Ω coaxial links to establish a compact, standardized four-channel point to point high speed connection between two automotive electronic modules.
Compared with multiple separate interfaces, this architecture improves connector density, harness packaging and channel management while supporting signal integrity, assembly efficiency and module to module connectivity for ADAS, smart cockpits and domain controllers.
Core Product Features ：
◆ Quad to Quad Four Channel High Density Interconnection
Quad HFM Z-coded interfaces at both ends integrate four independent coaxial channels into compact housings, enabling four-channel interconnection between two automotive modules. This reduces connector count and mating space while mechanical coding helps prevent mismating and improves ECU interface density, harness packaging and vehicle assembly efficiency.
◆ Four Independent 50Ω Links with Multiple Length Options
Four LEONI DACAR 302-4 50Ω coaxial cables independently carry CH1–CH4 without signal splitting, helping maintain characteristic impedance and signal integrity. Available in 1m, 2m and 5m lengths for different vehicle-routing requirements, with insertion loss and link budget evaluated for longer high-speed links.

Compatibility Statement
Verify HFM Interface, Coding and Four Channel Mapping
PCM-ZC-0065 uses AMK12D-1M4Z5-Z Quad HFM jacks at both ends, each designed to mate with the corresponding HFM plug/header on the equipment; the two cable-side jacks do not mate directly. Selection should verify the exact P/N, gender, housing, coding, cable group and mating interface.
Four independent CH1→CH1 through CH4→CH4 links should be defined by channel/cavity mapping to maintain a correctly matched 50Ω coaxial path.
Passive Design; Finished Harness Ratings Differ from Connector Platform Ratings
PCM-ZC-0065 is a passive cable assembly and does not convert GMSL, FPD-Link, MIPI A-PHY, USB, PCIe or other SerDes protocols. Although the HFM platform supports higher frequency and data-rate capabilities, the finished PCM-ZC-0065 design target remains DC–6GHz and should be validated for cable length, insertion loss, VSWR and manufacturing tolerances.
The 800Vrms value is a Hi-Pot/test voltage, not an operating voltage, while ≥110N refers to latch retention force rather than complete-harness cable pull force.
How to Select PCM-ZC-0065 ?
Verify Quad HFM Interfaces at Both Ends
PCM-ZC-0065 uses Quad HFM jacks at both ends. Verify device P/N, gender, coding, housing and mating interface. If one device uses individual FAKRA ports, select a Quad HFM-to-4×FAKRA breakout instead.
Verify Four-Channel Mapping
Define CH1–CH4 assignments for cameras, sensors or SerDes ports. Engineering drawings, harness labels, production assembly and electrical testing should use the same channel mapping to prevent misconnection.
Evaluate Link Budget by Length and Frequency
For 1m, 2m or 5m lengths, evaluate frequency, data rate, cable attenuation, insertion loss, return loss and system margin. A 5m high-speed link cannot be validated by the DC–6GHz rating alone.
Verify Protocol and Installation Requirements
Verify protocol, SerDes generation, ECU/camera model, temperature, vibration, EMC and bend radius. Dynamic locations such as robot arms or door hinges also require dedicated cable flex-life validation.
