DS100DF410SQ/NOPB Texas Instruments 接口-信号缓冲器、中继器 10GbE Quad Channel Retimer

1 Features 3 Description

1 The DS100DF410 is four channel retimers with • Each Channel Independently Locks to 10.3125

integrated signal conditioning. Each channel can Gbps independently lock to 10.3125 Gbps data rate to

• Lock Operation (typically under 15 ms) support 10GbE. The device includes a fully adaptive

• Low Latency (~300 ps) Continuous-Time Linear Equalizer (CTLE), Clock and

Data Recovery (CDR) and transmit De-Emphasis • Adaptive Equalization up to 34 dB Boost at 5 GHz

(DE) driver. The DS100DF410 also includes a self

• Adjustable Transmit VOD: 600 to 1300 mVp-p calibrating 5-tap Decision Feedback Equalizer (DFE)

• Adjustable Transmit De-emphasis to –12 dB to enable data transmission over long, lossy and

• Typical Power Dissipation (EQ+DFE+CDR+DE): crosstalk-impaired highspeed serial links to achieve

BER < 1×10-15 180 mW/channel .

• Programmable Output Polarity Inversion The programmable settings can be applied easily

• Input Signal Detection, CDR Lock using the SMBus (I2C) interface, or they can be

loaded via an external EEPROM. An on-chip eye Detection/Indicator

monitor and a PRBS generator allow real-time

• On-chip Eye Monitor (EOM), PRBS Generator measurement of high-speed serial data for system

• Single 2.5 V ±5% Power Supply bring-up or field tuning. Flow-through pinout and

• SMBus/EEPROM Configuration Modes single power supply make the DS100DF410 easy to

use.

• Operating Temperature Range of –40°C to 85°C

• WQFN 48-Pin, 7 mm x 7 mm Package

2 Applications • Front Port SFF 8431 (SFP+) Optical and Direct Attach Copper • Backplane Reach Extension, Data Retimer • Ethernet: 10GbE, 1GbE For other data rates and data transmission protocols, other pin-compatible devices in the retimer family can be used.
