Notes:

1. RF1 = 1.55 GHz, RF2 = 1.4 GHz, IF

= 1080 MHz., RFPWR=0 for all parameters unless otherwise noted.

2. From power up request (PWDNB

↑ or SENB↑ during a write of 1 to bits PDAB, PDIB, and PDRB in register 2) to RF and

IF synthesizers ready (settled to within 0.1 ppm frequency error). Typical settling time to 5 degrees phase error is

120

µs.

3. From power down request (PWDNB

↓, or SENB↑ during a write of 0 to bits PDAB, PDIB, and PDRB in register 2) to
