cc1200 modulation options at 915MHz

CC1200 supports 802.15.4g

Basically you have looked at the wrong standard.

Here's a great article on 802.15.4 variations:    http://electronicdesign.com/what-s-difference-between/what-s-difference-between-ieee-802154-and-zigbee-wireless  .

From it: The 802.15.4 category is probably the largest standard for low-data-rate WPANs. It has many subcategories. The 802.15.4 category was developed for low-data-rate monitor and control applications and extended-life low-power-consumption uses. The basic standard with the most recent updates and enhancements is 802.15.4a/b, with 802.15.4c for China, 802.15.4d for Japan, 802.15.4e for industrial applications, 802.15.4f for active (battery powered) radio-frequency identification (RFID) uses, and 802.15.4g for smart utility networks (SUNs) for monitoring the Smart Grid. All of these special versions use the same base radio technology and protocol as defined in 802.15.4a/b.

thansk for your responses
A couple fo questions. Given that "I have looked at the wrong spec" are you saying that the CC1200 only supports the modulation schemes defined in 802.15.4g.

The specification referenced in the initial query is dated 2011, and has been replaced/updated to the current specification dated 2012.  In the 2012 revision, table 66 refers to Filtered 2FSK for the 915MHz band.  GFSK is the equivalent, and the CC1200 supports this.
