Product details
Overview
EQCO62X20C1-I/8EX from Microchip Technology is a CoaXPress v1.1-compliant asymmetric coaxial equalizer IC designed for the frame grabber side of high-bandwidth machine vision links. It receives downlink data at up to 6.25 Gbps over 75Ω coax, equalizes attenuated signals adaptively, and transmits 21 Mbps uplink control signals with 130 mV amplitude and 11 ns rise/fall time - enabling nanosecond-precision triggering in semiconductor inspection systems.
For engineers reviewing the EQCO62X20C1-I/8EX datasheet, EQCO62X20C1-I/8EX pinout, EQCO62X20C1-I/8EX application, or EQCO62X20C1-I/8EX equivalent, this device is selected for CoaXPress 1.1-compliant camera interface designs requiring simultaneous power-over-coax (up to 900 mA), low-jitter equalization across 1.25–6.25 Gbps, and industrial temperature operation (−40°C to +85°C).
Technical Context
The EQCO62X20C1-I/8EX implements an auto-adaptive analog equalizer core that dynamically compensates cable attenuation using a time-continuous feedback loop, converging within microseconds upon signal detection. It supports multi-speed 8B/10B NRZ-coded downlink operation from 1.25 Gbps to 6.25 Gbps while maintaining ≤0.35 UI jitter at 6.25 Gbps over 45 m of Belden 1694A cable.
Its integrated LF pre-driver accepts 1.2V LVTTL uplink input (LFI), configures transmit amplitude via AmpR (1.2 kΩ typical) and rise/fall time via RiseR (10 kΩ typical), and outputs differential CML uplink signals onto SDIp/SDIn. The device uses on-chip 60Ω termination for inputs and 2×50Ω for outputs, with external 15Ω series resistors required on SDIp/SDIn.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EQCO62R20.3 | Same die, identical electrical specs and pinout; differs only in date code marking and minor packaging revision (C1 vs .3 suffix). | Direct drop-in replacement in all CoaXPress v1.1 frame grabber designs; validated for same Belden/Gepco/Canare cable performance. | Select EQCO62X20C1-I/8EX for new designs requiring latest Microchip wafer lot traceability and RoHS-6 compliance per DS60001302C rev C. |

FAQ
What is the primary function of the EQCO62X20C1-I/8EX in a CoaXPress system?
The EQCO62X20C1-I/8EX functions as the frame grabber-side equalizer and uplink transmitter in a CoaXPress v1.1 link. It receives high-speed downlink video (up to 6.25 Gbps) over coax, adaptively equalizes cable-induced distortion, and transmits low-speed control signals (21 Mbps) back to the camera - all while supporting power delivery up to 900 mA over the same cable. This dual-role operation is integral to the EQCO62X20C1-I/8EX architecture.
Does the EQCO62X20C1-I/8EX require external termination resistors on its differential inputs?
Yes, the EQCO62X20C1-I/8EX requires external 15Ω series resistors on both SDIp and SDIn pins. Although the device includes internal 60Ω termination to VCC on these inputs, the external resistors form part of the impedance-matching network for 75Ω coax and prevent signal reflections. This requirement is explicitly specified in the DS60001302C datasheet Section 1.1.1 and Table 2-1.
What is the maximum coax cable length supported by the EQCO62X20C1-I/8EX at 6.25 Gbps?
The EQCO62X20C1-I/8EX supports up to 68 meters of high-quality coax (e.g., Gepco VHD1100) at 6.25 Gbps, as verified in Table 2 of the DS60001302C datasheet. Performance varies by cable type: Belden 1694A achieves 40 m, while Canare L-7CFB reaches 46 m at the same rate. These values assume full CoaXPress v1.1 compliance with measured jitter ≤0.35 UI.
How is uplink amplitude and rise time configured on the EQCO62X20C1-I/8EX?
Uplink amplitude is set via the AmpR pin, which connects to VCC through a resistor - 1.2 kΩ yields 130 mV typical output. Rise/fall time is controlled by RiseR, where a 10 kΩ resistor delivers 11 ns (20%–80%). Both resistors must be present for LF driver activation; omission disables the uplink path. These configurations are defined in Sections 1.1.4–1.1.5 and Table 3-2 of the DS60001302C datasheet.
Is the EQCO62X20C1-I/8EX compatible with Power over CoaXPress (PoCXP)?
Yes, the EQCO62X20C1-I/8EX is fully compatible with PoCXP per the CoaXPress v1.1 standard. It supports up to 900 mA DC power delivery over coax using external ferrite beads (FBMH1608HM102) and a 10 µH inductor (1812PS_103), as shown in Figure 2-1. The device includes hot-plug protection and fast power switching capability, ensuring safe operation during live cable connection/disconnection.
