Baud High (BH) and Baud Low (BL)

Baud High (BH) and Baud Low (BL)

EEPROM Address: 40h and 41h respectively
Length: 1 Byte each
Default: FFh for BH and F1h for BL
Range: F4h, 84h – FFh, FFh (BH, BL)

There are two types of baud rates associated with a transceiver: RF Baud Rate and Serial Interface
Baud Rate. The RF Baud Rate is not configurable and is fixed at 882 Kbps. The Serial Interface Baud
Rate is configurable and can be programmed up to 882 Kbps. However, the maximum effective data
transmission rate is approximately 250 Kbps – 300 Kbps due to protocol overhead.

Baud High (BH) and Baud Low (BL) are used to configure the serial interface data rate between a
transceiver and its Host. Standard PC baud rate values are provided below:

Custom baud rates can be calculated using the following formula:

28.224 * 10

6

Baud Rate = 32.0 * (65,536 – BH, BL)

The calculated value must be within 3% of the actual value.

EEPROM Address: 43h and 44h respectively
Length: 1 Byte each
Default: 00h for 43h and 90h for 44h
Range: 00h – 07h for 43h, 01h – FFh for 44h

This parameter is only valid for transceivers operating in Transparent Modes 01 or 04. This parameter
is ignored when a transceiver is operating in all other modes. The Fixed Packet Length cannot exceed
2 KBytes.
