Notes
1. PSRR is defined as the ratio of the equivalent current change at the input (∆IIPhoto) to a change in supply voltage:
PSRR = -∆--∆-I--I-V-P---hC---o-C--t-o-
For example, a + 4 mV disturbance on VCC at 10 MHz will typically add an extra 8 nA to the photodiode current. The
external capacitor between pins DREF and GND has a large impact on the PSRR. The specification is valid with an
external capacitor of 1 nF. The PSSR is guaranteed by design.
2. The Pulse Width Distortion (PWD) is <5% over the whole input current range. The PWD is defined as:
PWD
=
p----u---l--s---e--T---w----i-d----t-h--
–
1
× 100%
where T is the clock period. The PWD is measured differentially with
PRBS pattern of 10−23.
3. All In(tot) measurements were made with an input capacitance of Ci = 1.2 pF. This was comprised of 0.7 pF for the
photodiode itself, with 0.3 pF allowed for the printed-circuit board layout and 0.2 pF intrinsic to the package. Noise
performance is measured differentially.
