The CX23888 and CX23102 can do it. Basically any IR pulse pattern your heart desires; within reason. And any carrier freq you want too; within reason. But let's be real, the cx23885, cx231xx, and cx25840 modules are nowhere near properly supporing suspend/resume for their main video and DMA functions, AFAIK.
