AGILENT Technologies has announced a 14-bit, 100MHz digitiser for the Agilent 93000 SOC Series that offers the highest performance for testing DOCSIS 2.0 and high-definition television (HDTV).
The new set-top box solution meets next-generation test requirements, increases throughput and lowers cost of test.
As consumers demand more interactive, two-way communication and entertainment services such as video conferencing, cable telephony and peer-to-peer gaming, the cable television industry is pressed to increase bandwidth and data rates.
The DOCSIS 2.0 standard increases upstream data rates to 30.7Mb/s, three times faster than before, enabling symmetric upstream and downstream bandwidth.
HDTV is also increasing in popularity because it provides a sharper picture than analogue TV, offering up to four times more pixels.
Both trends, DOCSIS 2.0 and HDTV, require higher-performance digital-to-analogue converters (DACs) to meet the higher data rate requirements. Higher performance impacts system-on-a-chip (SOC) and system-in-a-package (SIP) devices for set-top box, cable modem and digital television (DTV) applications.
The Agilent 14-bit, 100-MHz digitiser provides exceptional total harmonic distortion (THD) and spurious-free dynamic range (SFDR) performance, meeting test requirements while increasing throughput.
The digitiser's industry-leading performance of -85dBc SFDR has the capability to test 12-bit VHF DACs, delivering accurate and optimal performance for characterisation and production test of upstream DOCSIS 2.0 and HDTV video DACs.
In addition, the digitiser minimises averaging, which reduces test time and lowers cost of test. Cost of test further decreases with the Agilent 93000 SOC platform architecture.
A high pin count of up to 1024 pins and a test processor-per-pin architecture enables high-efficiency dual or quad-site test.
Throughput can be driven even higher with concurrent test (testing multiple functional blocks in an SOC simultaneously).
