GENERAL DESCRIPTION

The AD9511 provides a multi-output clock distribution function along with an on-chip PLL core. The design emphasizes low jitter and phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements also benefit from this part. The PLL section consists of a programmable reference divider (R); a low noise phase frequency detector (PFD); a precision charge pump (CP); and a programmable feedback divider (N). By connecting an external VCXO or VCO to the CLK2/CLK2B pins, frequencies up to 1.6 GHz may be synchronized to the input reference.

There are five independent clock outputs. Three outputs are LVPECL (1.2 GHz), and two are selectable as either LVDS (800 MHz) or CMOS (250 MHz) levels. Each output has a programmable divider that may be bypassed or set to divide by any integer up to 32. The phase of one clock output relative to another clock output may be varied by means of a divider phase select function that serves as a coarse timing adjustment. One of the LVDS/CMOS outputs features a programmable delay element with full-scale ranges up to 10 ns of delay. This fine tuning delay block has 5-bit resolution, giving 32 possible delays from which to choose for each full-scale setting.

The AD9511 is ideally suited for data converter clocking applications where maximum converter performance is achieved by encode signals with subpicosecond jitter.

The AD9511 is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. An external VCO, which requires an extended voltage range, can be accommodated by connecting the charge pump supply (VCP) to 5.5 V. The temperature range is ?40°C to +85°C.

Parameter Min Typ Max Unit Test Conditions/Comments NOISE CHARACTERISTICS

In-Band Noise of the Charge Pump/ Phase Frequency Detector (In-Band Means Within the LBW of the PLL) The synthesizer phase noise floor is

estimated by measuring the in-band phase noise at the output of the VCO and

subtracting 20logN (where N is the N divider value).

@ 50 kHz PFD Frequency ?172 dBc/Hz @ 2 MHz PFD Frequency ?156 dBc/Hz @ 10 MHz PFD Frequency ?149 dBc/Hz @ 50 MHz PFD Frequency ?142 dBc/Hz PLL Figure of Merit ?218 + 10 × log (f PFD ) dBc/Hz Approximation of the PFD/CP phase noise

To Unlock After Lock (Hysteresis)4 Selected by Register 0Dh. Low Range (ABP 1.3 ns, 2.9 ns Only) 7 ns <5> = 1b. High Range (ABP 1.3 ns, 2.9 ns) 15 ns <5> = 0b. High Range (ABP 6 ns) 11 ns <5> = 0b.

1 REFIN and REFINB self-bias points are offset slightly to avoid chatter on an open input condition.

2

CLK2 is electrically identical to CLK1; the distribution only input can be used as differential or single-ended input (see the Clock Inputs section). 3

Example: ?218 + 10 × log(f PFD ) + 20 × log(N) should give the values for the in-band noise at the VCO output. 4

For reliable operation of the digital lock detect, the period of the PFD frequency must be greater than the unlock-after-lock time.
