Infineon Technologies CYP15G0403DXB-BGI

Overview

CYP15G0403DXB-BGI from Cypress Semiconductor Corporation is an independent-clock quad HOTLink II™ transceiver IC for high-speed serial interconnects. It implements four fully autonomous channels, each supporting 195–1500 MBaud serial data rates with 8B/10B encoding, dual PECL-compatible differential I/O per channel, and integrated PLL-based clock recovery. It is used in multi-protocol aggregation switches requiring simultaneous ESCON, DVB-ASI, and SMPTE-259M-compliant links over fiber or backplane traces.

For engineers reviewing the CYP15G0403DXB-BGI datasheet, CYP15G0403DXB-BGI pinout, CYP15G0403DXB-BGI application, or CYP15G0403DXB-BGI equivalent, key selection criteria include per-channel reference clock independence, aggregate 12 Gbps throughput, BIST-enabled at-speed link validation, and support for both encoded (8B/10B) and uncoded 10-bit parallel interfaces.

Technical Context

The CYP15G0403DXB-BGI integrates four independent transmit/receive channels, each with dedicated reference clock inputs (REFCLKA–D±), internal PLLs eliminating external loop filters, and selectable TX/RX clocking modes (local or recovered). Each channel supports dual differential PECL-compatible serial I/O pairs (e.g., OUTA1±/OUTA2±, INA1±/INA2±) with source-matched 50Ω drive and no external bias resistors required.

Its MultiFrame™ Receive Framer provides bit/byte alignment, K28.5 comma detection, and low-latency framing options. The parallel interface uses synchronous LVTTL signaling with configurable TXCKSEL/RXCKSEL control, while JTAG boundary scan and built-in BIST enable system-level diagnostics without external test equipment.

FAQ

Does CYP15G0403DXB-BGI support 8B/10B encoding on all four channels simultaneously?

Yes. Each of the four channels includes a dedicated 8B/10B encoder/decoder block that operates independently. Encoding can be enabled or bypassed per channel via the DECMODE[A..D] configuration bits, allowing mixed-mode operation-for example, two channels using 8B/10B for DVB-ASI and two using uncoded 10-bit data for proprietary protocols.

What is the minimum supported serial data rate per channel?

The minimum guaranteed serial data rate is 195 MBaud per channel, verified across temperature and voltage ranges per the Rev. *F datasheet. This enables compatibility with legacy ESCON (176 MBaud nominal) and DVB-ASI (270 MBaud) systems when operating with margin.

Can the CYP15G0403DXB-BGI operate with a single-ended reference clock?

No. All REFCLKA–D inputs require differential PECL-compatible signaling (REFCLKx+ and REFCLKx−). Single-ended clock sources must be converted using a dedicated differential driver or transformer; the device does not accept LVCMOS or LVTTL clock inputs directly.

Is the 256-ball BGA package RoHS-compliant and lead-free?

Yes. The CYP15G0403DXB-BGI is offered in a Pb-free, RoHS-compliant 256-ball thermally enhanced BGA package, with JEDEC-standard marking and solder reflow profile compatible with SnAgCu (SAC305) processes.
