VSC7650 and VSC7651
4x 3.125 Gbps Receiver Arrays with Integrated Limiting Amplifiers
Features:
Common Cathode Detector Array; CML or PECL Outputs (VSC7650)
Separate Cathode Detector Array; LVDS Outputs (VSC7651)
250 μm Channel Spacing
Sensitivity: –21 dBm Typical (at 850 nm)
High Transimpedance Gain: 70 k
Low Power: 180 mA at +3.3 V Supply
Individual Per Channel Control
LOS Detect
Photocurrent Monitor for Optical Alignment
Photodiode Bias Filter
Available as Bare Die
The VSC7650 and VSC7651 are high-performance, four-channel receiver
arrays designed to operate up to 3.125 Gbps for use in 10 Gbps Very
Short Reach (VSR) parallel module or 10GBASE-LX4 Coarse Wavelength
Division Multiplexing (CWDM) applications. Each channel includes a
bias filter, a transimpedance amplifier, a limiting amplifier, an output
driver, and Loss of Signal (LOS) detect circuitry. Signal monitors for each
channel facilitate optical alignment. The VSC7650 and VSC7651 are
die-level products that are fully tested at the maximum operating speed
to guarantee performance and improve module manufacturing yields.
The VSC7650 and VSC7651 are pin and functional compatible; the
designer has the flexibility to choose the output level version as required
by system architecture and performance.

VCSEL Modulation and Bias Currents
Negative Peaking
Overcurrent Threshold
Digital Serial Control Interface
Temperature and Overcurrent Monitors
AC- or DC-coupled Inputs
Automatic Shutdown for Data Eye Protection
250 μm Channel Spacing
IBIAS < 6.4 mA, 27 μA Resolution
IMOD < 16 mA, 50 μA Resolution
Rise and Fall Times of >50 ps and <110 ps
Available as Bare Die
The VSC7640 is a high-performance, four-channel VCSEL driver array
designed to operate up to 3.125 Gbps for use in 10 Gbps Very Short
Reach (VSR) parallel module applications. This device provides four indi-
vidual VCSEL driver channels, a serial programmable interface tempera-
ture sensor for each channel, a temperature sensor, an overcurrent sen-
sor and control for each channel, and monitoring logic for eye safety shut-
down and power-on reset. The VSC7640 is designed to interface to a
four-channel VCSEL array and to work in conjunction with a microcon-
troller. Unlike other competitive solutions the VSC7640 features a program-
mable negative peaking control to compensate for VCSEL slow tail cur-
rents. The VSC7640 is a die-level product that is fully tested at the maximum
operating speed to guarantee performance and module manufacturing
yields.
