Product details
Overview
EQCO62X20C1T-I/8EX from Microchip Technology is a CoaXPress v1.1-compliant asymmetric coaxial equalizer IC for the frame grabber side of high-bandwidth machine vision links, supporting downlink data rates up to 6.25 Gbps and uplink at 21 Mbps over a single 75Ω coax cable, with integrated adaptive equalization, 1.2V supply operation, and -40°C to +85°C industrial temperature range.
For engineers reviewing the EQCO62X20C1T-I/8EX datasheet, EQCO62X20C1T-I/8EX pinout, EQCO62X20C1T-I/8EX application, or EQCO62X20C1T-I/8EX equivalent, this device serves as the high-speed receiver in bidirectional CoaXPress camera interfaces requiring precise jitter control (<0.35 UI at 6.25 Gbps), power-over-coax support (up to 900 mA), and RF-optimized QFN layout for Belden 1694A/Canare L-7CFB cable compatibility.
Technical Context
The EQCO62X20C1T-I/8EX implements an auto-adaptive analog equalizer core that dynamically compensates cable attenuation across 1.25–6.25 Gbps using time-continuous feedback, with variable gain and multi-speed 8B/10B NRZ signal recovery. Its active splitter/combiner architecture enables simultaneous full-duplex operation on one coax line.
It integrates a low-frequency (21 Mbps) LVTTL uplink transmitter with programmable amplitude (130 mV typical) and rise/fall time (11 ns typical), driven by external Ramp and RiseR resistors, while its CML differential inputs (SDIp/SDIn) feature on-chip 60Ω termination and require external 15Ω series resistors for impedance matching to coax.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Downlink Data Rate | Up to 6.25 Gbps - supports CoaXPress v1.1 maximum bandwidth for HD/high-speed imaging |
| Uplink Data Rate | 21 Mbps - enables nanosecond-precision triggering and camera control from frame grabber |
| Supply Voltage | 1.2 V ±5% - low-voltage operation reduces power consumption to 60 mA typical |
| Operating Temperature | -40°C to +85°C - qualified for industrial machine vision and embedded inspection systems |
| Differential Input Impedance | 60 Ω to VCC - internal termination simplifies interface to 75Ω coax via external 15Ω series resistors |
| Equalizer Output Jitter | ≤0.35 UI at 6.25 Gbps - meets CoaXPress v1.1 jitter budget for reliable 45m link on Belden 1694A |
| Uplink Transmit Amplitude | 130 mV (typical) - optimized to minimize crosstalk with high-speed downlink channel |
Pinout & Package
EQCO62X20C1T-I/8EX is housed in a 16-pin, 4 mm × 4 mm × 0.9 mm body, 0.65 mm pitch QFN package with exposed thermal pad, RoHS-compliant and Pb-free per JEDEC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 4, 9, 12, 13, 16) | Power ground reference | Single-point grounding required for RF integrity; pins 13/16 connect to exposed thermal pad |
| VCC (Pins 13, 16) | 1.2V power supply input | Supplies core logic and equalizer; decoupling capacitors (C2–C6) required per datasheet layout |
| SDIp / SDIn (Pins 2, 3) | Differential CML input pair | Receives attenuated downlink signal; on-chip 60Ω termination to VCC; external 15Ω series resistors mandatory |
| SDOp / SDOn (Pins 10, 11) | Differential CML output pair | Drives recovered 100Ω LVDS-like signal to FPGA/ASIC; includes 2×50Ω on-chip termination |

| AmpR (Pin 6) | Uplink amplitude programming | Resistor to VCC sets uplink output swing (1.2 kΩ → 130 mV); omission disables LF driver |
| RiseR (Pin 7) | Uplink rise/fall time programming | Resistor to VCC sets edge timing (10 kΩ → 11 ns); critical for jitter and crosstalk control |
| NC (Pins 8, 14, 15) | No-connect | Internally unused; must be left floating per design specification |

FAQ
What is the primary function of the EQCO62X20C1T-I/8EX in a CoaXPress system?
The EQCO62X20C1T-I/8EX functions as the frame grabber-side high-speed receiver in a CoaXPress v1.1 link. It equalizes and recovers downlink data up to 6.25 Gbps from coax, while transmitting low-speed uplink commands (21 Mbps) back to the camera. Its integrated adaptive equalizer, programmable uplink driver, and RF-optimized QFN package make it essential for deterministic, single-cable machine vision interfaces. EQCO62X20C1T-I/8EX replaces discrete equalizer + serializer combinations with a single IC solution.
Does EQCO62X20C1T-I/8EX support Power over CoaXPress (PoCXP)?
Yes, EQCO62X20C1T-I/8EX supports PoCXP up to 900 mA DC through external components: a 10 µH inductor (L1), two 1 kΩ ferrite beads (Fb1/Fb2), and appropriate filtering capacitors. The IC includes hot-plug protection to withstand pre-applied 24V on the coax during connection. EQCO62X20C1T-I/8EX does not integrate the power switch or relay but provides the signal path and protection necessary for compliant PoCXP implementation per CoaXPress v1.1.
What are the key layout requirements for EQCO62X20C1T-I/8EX to meet CoaXPress v1.1 specifications?
To meet CoaXPress v1.1, EQCO62X20C1T-I/8EX requires strict PCB layout adherence: a cut-out in ground/power planes beneath SDIp/SDIn pins to minimize parasitic capacitance, no vias in the high-speed signal path, 100Ω differential routing for SDOp/SDOn outputs, and precise placement of external 15Ω series resistors and recommended ferrite beads (FBMH1608HM102) and inductor (1812PS_103). EQCO62X20C1T-I/8EX performance degrades significantly if these RF layout rules are violated-even minor trace length changes affect jitter and return loss.
How does the adaptive equalizer in EQCO62X20C1T-I/8EX operate, and what cable lengths does it support?
The EQCO62X20C1T-I/8EX adaptive equalizer uses a time-continuous feedback loop to automatically configure a multi-pole analog filter that compensates for frequency-dependent cable loss. It converges within microseconds upon valid signal detection and supports downlink rates from 1.25 to 6.25 Gbps. At 6.25 Gbps, EQCO62X20C1T-I/8EX achieves up to 68 m on Gepco VHD1100 or 40 m on Belden 1694A; at 1.25 Gbps, it extends to 212 m on Gepco VHD1100-enabling flexible deployment across diverse coax types without manual tuning.
What is the purpose of the AmpR and RiseR pins on EQCO62X20C1T-I/8EX, and how are they configured?
AmpR (Pin 6) and RiseR (Pin 7) are resistor-programmed inputs that set the amplitude (130 mV typical) and rise/fall time (11 ns typical) of the 21 Mbps uplink transmitter. Connecting AmpR to VCC via 1.2 kΩ sets nominal output swing; connecting RiseR to VCC via 10 kΩ sets edge timing. Omitting either resistor disables the uplink driver. These pins allow EQCO62X20C1T-I/8EX to optimize crosstalk rejection against the high-speed downlink-critical for maintaining signal integrity in full-duplex operation.
