SERIAL BAUD RATE (MBaud)
WORD RATE (MWords/sec)
is unique. The user serial data
rate is calculated as:
Serial Data Rate =
(–––––) (–––––) =
960 MBits/sec
The baud rate includes an addi-
tional four encoding bits (20 bits
total) that the HDMP-1032/34
G-Link chipset transmits. The
serial baud rate is calculated as:
Serial Baud Rate =
(–––––) (–––––) =
1200 MBaud
Example 2 (Overlapping Ranges)
Some applications may have a
parallel word rate that seems
to fit in two ranges of opera-
tion. For example, a 42.5 MHz
(42.5 MWord/s) parallel data
rate falls within two ranges:
DIV1/0 = (0/0) and DIV1/0 =
(0/1). According to the table, a
setting of DIV1/0 = (0/1) gives
Setting the Operating Data Rate Range
The HDMP-1032/1034 chipset
can operate from 260 MBaud to
1400 MBaud. It is divided into
three operating data ranges with
each range selected by setting
DIV1/0 as shown in the Typical
Operating Rates table. Two
examples have been provided in
order to help in understanding
and using this table.
Example 1 (Unique Range)
It is desired to transmit a 16 bit
parallel word operating at a fre-
quency of 60 MHz (60 MWord/
sec). Both the Tx and Rx must
be set to a range that covers this
word rate. According to the table
only a setting of DIV1/0 = (0/0)
allows a parallel input word rate
of 40 to 70 MHz. This range
setting easily accommodates the
required 60 MHz word rate and
an upper rate of 45 MHz while a
setting of DIV1/0 = (0/0) gives a
lower rate of 40 MHz. The upper
and lower data rates stated in the
tables are typical values unless
indicated by (min) or (max) and
may vary between individual parts.
However, each transmitter/receiver
has overlapping ranges of opera-
tion providing continuous band
coverage from 260 to 1400 MBaud.
In this example, each transmitter/
receiver will permit a 42.5 MHz
parallel data rate but it is sug-
gested that DIV0 be tied to a
jumper that can be set either to
logic ‘1’ (open allowing DIV0 to
float high) or logic ‘0’ (ground).
This allows the design to accom-
modate both ranges for maximum
flexibility. This technique is rec-
ommended whenever operating
near the upper and lower ends of
two adjacent word rate ranges.
