8 Channel 10:1 Serializer with IEEE 1149.1 and At-Speed

BIST

General Description

Features

n IEEE 1149.1 (JTAG) Compliant and At-Speed BIST test

mode.

The SCAN928028 integrates eight serializer devices into a

single chip. The SCAN928028 can simultaneously serialize

up to eight 10-bit data streams. The 10-bit parallel inputs are

LVTTL signal levels. The serialized outputs are LVDS signals

with extra drive current for point-to-point and lightly loaded

multidrop applications. Each serializer block in the

SCAN928028 operates independently by using strobes from

a single shared PLL.

n All 8 channels synchronous to one parallel clock rate,

from 25 to 66 MHz

n Duplicates function of multiple DS92LV1021 and ’1023

10-bit Serializer devices

n Serializes from one to eight 10-bit parallel inputs into

data streams with embedded clock

The SCAN928028 uses a single +3.3V power supply with a

typical power dissipation of 740mW (3.3V / PRBS / 66 MHz).

Each serializer channel has a unique power down control to

further conserve power consumption.

n Eight 5 mA modified Bus LVDS outputs that are capable

to drive double terminations

Speed Test - PRBS generation to check LVDS

transmission path to SCAN921224, SCAN921226,

SCAN921260, or SCAN926260

For high-speed LVDS serial data transmission, line quality is

essential, thus the SCAN928028 includes an SPEED

n On chip filtering for PLL

TEST function. Each Serializer channel has the ability to

internally generate a PRBS data pattern. This pattern is

received by specific deserializers (SCAN921224) which

have the complement PRBS verification circuit. The deseri-

alizer checks the data pattern for bit errors and reports any

errors on the test verification pins on the deserializer.

n 740mW typ power dissipation (loaded, PRBS, 66MHz,

3.3V)

n High impedance inputs and outputs on power off

n Single power supply at +3.3V (+/-10%)

n 196-pin LBGA package

n Industrial temperature range operation: -40 to +85˚C

Information section in this datasheet.
