SAN JOSE, Calif., March 6, 2019 /PRNewswire/ -- Integrated
Device Technology, Inc. (IDT) (NASDAQ: IDTI) today introduced its
new GX7647x 64G linear driver family, in die form, for optical
integrated modules, for 400G/600G coherent applications.
Cloud and telecom operators continue to drive the demand for
increased data rates. Coherent technology 100G/200G pluggable
modules for telecom applications have had huge success in the last
few years. 400ZR is an interoperability standard currently
being developed by the Optical Internetworking Forum (OIF), that
allows for 400G data rate with 64Gbaud DP-16QAM, and is expected to
play an important role to the continuous growth of the coherent
market, especially in the Data Center Interconnect (DCI). Top
performance optical modulator drivers are in high demand in those
applications, and in addition to the conventional Lithium
Niobate and Indium Phosphide (InP) optical modulators, Silicon
Photonics technology shows promise for photonic integration circuit
platforms used in high-speed optical transceivers. A driver
design optimized to take into account optical modulator properties
provides superior performance of the integrated optical modules,
such as OIF defined High Bandwidth Coherent Driver Modulator
(HB-CDM) and Integrated Coherent Transmitter-Receiver Optical
Sub-Assembly (IC-TROSA).
The IDT® GX7647x series comprises 4 channels, 64G linear optical
modulator drivers for 400G/600G coherent applications with a
16QAM/64QAM modulation format. The GX76470/1/3, GX76472
and GX76474 drivers are designed with the frequency response,
output impedance, and the driving voltage swing to obtain the best
performance working in tandem with the Indium
Phosphide, Lithium Niobate and Silicon Photonics optical
modulators, respectively. Those drivers are suitable for 400G
ZR, Metro, and DC applications, and are compliant with OIF
requirements for highly integrated optical sub-assembly modules,
such as HB-CDM and IC-TROSA. The GX7647x provide the advanced
features, which differentiate the performance of the customer's
HB-CDM and IC-TROSA, including:
- 50GHz bandwidth with control of 10dB peaking at around
40GHz
- Frequency response tunability through SPI registers to optimize
the E/O response of the optical modules
- Large output voltage swing of 2.8Vppd for GX76470/1/2/3 and
4Vppd for GX76472 and GX76474
- High linearity of less than 1% THD up to 4Vppd output
- Low channel to channel crosstalk of less than -35dB up to
50GHz
- Low power consumption GX76474, open collector type driver for
the optical modulator based on Silicon Photonics technology
"The GX7647x driver family covers various types of coherent
optical modulators," said Dr. Koichi
Murata, marketing director, telecom, for IDT's optical
interconnects division. "The performance tunability to each optical
modulator and the extreme high performance in bandwidth, linearity,
driving voltage, crosstalk and power consumption are key to
providing the design margin of the coherent optical modules such as
HB-CDM and IC-TROSA for 400ZR and DCI applications."
IDT has sampled customers with the GX7647x series and production
is expected to begin in Q2 2019.
