Infineon Technologies CYP15G0403DXB-BGXC

Overview

CYP15G0403DXB-BGXC from Cypress Semiconductor is an independent-clock quad-channel HOTLink II™ transceiver IC for high-speed serial interconnects. It supports 195–1500 MBaud per channel, delivers up to 12 Gbps aggregate throughput, features dual PECL-compatible differential I/O per channel, integrated 8B/10B encoding/decoding, and operates from a single 3.3V supply. Used in multi-protocol routers and aggregation equipment requiring per-channel rate independence and standards-compliant serial links.

For engineers reviewing the CYP15G0403DXB-BGXC datasheet, CYP15G0403DXB-BGXC pinout, CYP15G0403DXB-BGXC application, or CYP15G0403DXB-BGXC equivalent, key selection considerations include per-channel reference clock autonomy, PECL-compatible differential signaling, 8B/10B encode/decode capability, BIST-enabled at-speed link validation, and support for ESCON, DVB-ASI, SMPTE-259M/292M, Fibre Channel, and Gigabit Ethernet physical layer requirements.

Technical Context

The CYP15G0403DXB-BGXC implements four fully independent transmit/receive channels, each with its own PLL-based clock and data recovery (CDR), enabling simultaneous operation at different baud rates (195–1500 MBaud) and distinct data formats (8-bit uncoded or 10-bit 8B/10B encoded). Each TX channel includes a programmable serializer with x10/x20 bit-rate multiplication, while each RX channel integrates a MultiFrame™ framer supporting comma detection, bit/byte alignment, and low-latency mode.

Its parallel interface uses synchronous LVTTL signaling with configurable clocking options (local REFCLKx or recovered RXCLKx), and supports JTAG boundary scan and built-in self-test (BIST) for full at-speed link verification. The device bypasses internal 8B/10B logic when externally encoded data is presented, preserving system-level encoding flexibility.

FAQ

Is CYP15G0403DXB-BGXC pin-compatible with CYV15G0403DXB-BGXC and CYW15G0403DXB-BGXC?

Yes-CYP15G0403DXB-BGXC, CYV15G0403DXB-BGXC, and CYW15G0403DXB-BGXC share identical 256-ball BGXC package, pin assignment, and LVTTL/PECL interface timing. Functional differences are limited to internal compliance logic and maximum data rate limits, not physical or electrical interface behavior.

Does CYP15G0403DXB-BGXC support 8B/10B encoding for all four channels simultaneously?

Yes-the device contains four independent 8B/10B encoders and decoders, one per channel. Each can be enabled or bypassed individually via configuration registers, allowing mixed-mode operation (e.g., two channels encoded, two uncoded) without hardware change.

What is the role of the dual differential PECL outputs per channel?

Each channel provides two independent PECL-compatible differential output pairs (e.g., OUTA1± and OUTA2±) to drive separate physical media-such as redundant fiber paths or split-copper traces-enabling link-level redundancy, load sharing, or multi-drop topologies without external multiplexing.

Can CYP15G0403DXB-BGXC operate with only one reference clock applied?

No-each of the four channels requires its own dedicated differential reference clock (REFCLKA± through REFCLKD±) to maintain independent rate operation. Applying a common clock to all REFCLKx inputs forces synchronous operation and forfeits the core "independent clock" capability defined in the HOTLink II architecture.
