High speed (>30KHz) 10-bit PWM generator
A number of microcontrollers can do this.  You want 30 kHz PWM with 10 bits of duty cycle resolution.  That means the PWM generator needs a clock of (30 kHz)(1023) = 30.7 MHz.  A EP series dsPIC 33 or PIC 24 can run at, and clock its pwm generators, at nearly twice that frequency.  There are also some "high speed" PWM generators available on these parts that have their own oscillator and PLL, and run the PWM at about 1 GHz.

What you're asking for really isn't all that exotic.
