PHO28014

4-channel 25.8G/28Gbps integrated CDR transimpedance amplifier

Product details Technical documentation Design and development

Product details

Parameter Package | Pin | Size Characteristic Describe
Part Number PHO28014
Description Four Channel 25G / 28G CDR with Integrated TIA
Max Data Rate(Gbps) 28
Core supply voltage (V) 1.8,3.3
Features I2C
The chip size is 3.1mm x 2mm

-12dBm typical sensitivity: BER 1E-12, 0.5A/W, 25.78Gbps,

ER=4dB

Low power consumption: typical 150mW/ch, bypass CDR 100mW/ch

High sensitivity limiting amplifier and LOS threshold

Reference free CDR with programmable PLL BW and bypass mode

Each channel is individually programmable to output swing, turn off output, and de emphasize/power off

Digital diagnostic monitoring interface

Output four channel average PD current monitoring (RSSI) through a single pin

Supports chip junction temperature from -40 ° C to+95 ° C

Extract clock output fb/16 (monitoring clock).

PHO28014 is a four-way 25.78 Gbps/28.05 Gbps transimpedance amplifier that integrates CDR and equalizer, and can be used as a complete single-chip transmission solution in optical modules. The center to center spacing of the output pads is 250 μ m to ensure compatibility with standard optical interfaces. Each channel includes a high-sensitivity bandwidth adjustable TIA, high-performance CDR, and an output swing adjustable driver with 3-tap de emphasis, all of which can be controlled through an I2C serial interface. The non reference clock CDR of PHO28014 can be re timed at 25.78 Gbps, 27.95 Gbps, and 28.05 Gbps. Traditional or non-standard data rates can be supported through bypass functionality.

The bare chip size of PHO28014 is 3.1mm x 2mm, supplied in waffle box packaging.
